All apps with more than 3 commands stop working

[RustyP]

Really strange, overnight ALL my apps have now got issues without showing errors.

So i have a gallery attached to SharePoint data and an OnSelect button to complete the following commends.

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Navigate(CurrentCosttoComplete ,Fade); 

basicly collects the selected data and navigates to anther page which displays it and can be edited.

This used to work fine for ages with no issues but now its always misses the last commend! If i change the order off the above commands it will always miss the last one at the bottom, i know this because i have used the Monitoring tool. The way its shown above, it will not navigate to the new page, so frustrating. Also there are no error.

The really strange this is, this is also happened on my other app and Evern when i go back to a previous version that i know worked it still doesn't work!

Has anyone else experienced this?

No, that's strange.

If you need to hurry up and work around it, does putting something arbitrary like 

Set(nullVar,Blank())

as the very last line, make all of the lines above it work?

I recommend you try to follow these steps below (or get your admin to follow them) to get more advanced, personalized help, as you should not be encountering this issue: 
Enter a support request through new new support center - Power Platform

Hi @poweractivate 

Thanks for your message, i tried what you suggested with no luck!

To add to this the below icons are now missing, this on different computers!

Im sure that should no be happening, very strange

[RustyP]

@poweractivate and this?

[cwebb365]

I would put in a support request ASAP. I hope this isn't a new PowerApps backend update that could potentially start affecting everyone, that could be bad! But yeah, If you haven't get the support wagon rolling.

Hey @cwebb365 

Just tried putting a support request in and its a nightmare!

You just get put through to a virtual help which is no help at all....

and when i put in a request for support i get an error.

I think you could be right, this seems to be an issue with Microsoft and not my app or apps 

[RustyP]

Iv just found out that over people are losing their icons on all their apps they have built but are not having the same issues as me, but then they might not be using the apps the same!

Im at a loss!

@RustyP 

Try to follow all the steps here by using the below link, follow the steps all the way through, including the ones where you get to start the ticket itself.

Use this link to follow the steps to create a new Power Platform support ticket

You are saying that even when you follow all the steps, you get an error to create the ticket itself too?

@RustyP 

I am not able to reproduce the issue myself with the commands, I also don't get the issue with the icons, but I suspect there may be some sort of internal issues, perhaps especially for some particular kinds of existing apps, since it seems to be raised more than once recently by multiple people.

For the issue where it misses the last command, does putting two lines at the very end of each formula that has this issue, help?

Set(nullVar01,Blank());
Set(nullVar02,Blank())

If not, does it help if each line ending with a semicolon (;) is separated by a new line or line feed like this?

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Navigate(CurrentCosttoComplete ,Fade); 
Set(nullVar01,Blank());
Set(nullVar02,Blank())

as opposed to this:

ClearCollect(CurrentCTC,ThisItem);ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);Navigate(CurrentCosttoComplete ,Fade);Set(nullVar01,Blank());Set(nullVar02,Blank())

If not, does it make a difference if the very last line has a semicolon too?

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Navigate(CurrentCosttoComplete ,Fade); 
Set(nullVar01,Blank());
Set(nullVar02,Blank());

If not, can you do the following steps for all affected formulas (but try it with just one affected formula first) see if the below steps help?

1. Use this formula, only two lines

Set(nullVar01,Now());
Set(nullVar02,Now());

2. Cause the property of the above formula to be triggered

3. Go to

     a. Ellipses to the right of Settings -> and then

     b. Variables and check that the variables have updated with the current time and date

Confirm that the current date and time is there above.

If that worked, now replace the affected formula with

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Navigate(CurrentCosttoComplete ,Fade); 
Set(nullVar01,Now());
Set(nullVar02,Now());

If not, try like this

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Set(nullVar01,Now());
Navigate(CurrentCosttoComplete ,Fade); 
Set(nullVar02,Now());

or this

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Set(nullVar01,Now());
Navigate(CurrentCosttoComplete ,Fade); 
Set(nullVar02,Now());
Set(nullVar03,Now());

and also try this

ClearCollect(CurrentCTC,ThisItem);
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);
Set(nullVar01,Now());
Navigate(CurrentCosttoComplete,ScreenTransition.Fade); 
Set(nullVar02,Now());
Set(nullVar03,Now());

Does it help @RustyP ?

If any of the above helps, you can do that for now,

however, you should definitely not have to do anything of the sort.

I would recommend to follow these steps as soon as possible to raise the support ticket.

It's also possible none of the above will help, so you should try to get in touch with support as soon as possible.

@RustyP 

Also pay attention to this line

ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);

Try getting rid of any line related to Attachments, see if this helps

If it does, the issue may be specifically related to using Attachments or dealing with Attachments.

If so, try seeing if these variations work:

//original
ClearCollect(CurrentCTCAttachmenets,ThisItem.Attachments);

//variation
ClearCollect(CurrentCTCAttachmenets,First(ThisItem.Attachments));

//variation
ClearCollect(CurrentCTCAttachmenets,First(ThisItem).Attachments);

//variation
ClearCollect(CurrentCTCAttachmenets,First(First(ThisItem).Attachments));

You should certainly not have to do that. I doubt any of the above would work, because I am unsure of the exact issue here as well.

However, at least see if the issue might be specifically when you have any lines in the formula related to an Attachment of any kind.

If so, this may be valuable information to provide to support
