Gallery control broken?

[Owizardo]

Is anyone having problems with Galleries recently? For example, my PowerApps application is completely broken and getting the message: 

Uncaught ReferenceError: Label14__9Outputs is not defined

If I open my developper console in my chrome I see this error:

Uncaught ReferenceError: Label14__9Outputs is not defined

I traced it down to a gallery, removed the label but then it complains about something else in my gallery. The only way I was able to get pass this was removing the gallery all together. Tried recreating it from scratch about 10 times and keep getting errors that prevent. So can no longer use galleries ...

I went as far as recreating my application (that took me months by the way) from scratch and now my other application is acting up, for example vibility with the condition:

If(CountRows(Gallery.AllItems) = 0, false, true)

This seems to work on the Powerapps editor (After pasting it 2-3 times tough). But loading the application, nothing happens ...

Some help would be greatly appreciated.

EDIT: 

Scratch finally got the visibility to work, the probleme was with: 

If(CountRows(Gallery.AllItems) = 0, false, true)

Changed it to this:

If(CountRows(Collection) = 0, false, true)

 For some odd reason Gallery.AllItems always returns 0 ... again galleries seem very buggy at the moment. All this was working fine last week ... started today for me.

Hi, if you want to test a broken app, here is my broken one. Nothing works

@keshamer I can verify that you are experiencing the same issue.  We are actively working on a hotfix.  I will keep the thread posted as we know more.

@_Corey_  Could you confirm if the issue is only with gallery control? I'm having trouble with other controls too. My start screen is messed up.

Update: A hotfix has been validated and is approved for deployment. Once deployed, you will need to edit your app(s) in Studio and re-publish. I will update this thread once hotfix deployment is complete.

@Anonymous We are not aware of this issue affecting other controls directly; however, under certain conditions, the gallery issue may affect the consistency of the app and cause other controls to operate incorrectly.  If it is enabled, you may try disabling Formula-level error manangement in App settings -> Advanced settings to see if this improves the overall behaviour.

Update: We are still working to deploy the hotfix. We encountered a technical issue which prevented us from deploying sooner. I will update this thread again once hotfix deployment is complete.

I thought I was the only one experiencing this problem. 

I also have the visibility problem.

In a gallery if I have this as the visible property: CountRows(compGalleryItems.AllItems) > 0

When I run the app, the gallery is hidden (which means the above formula is returning false, but when I drag a label on and set its text to CountRows(compGalleryItems.AllItems), the result is 3 (for example). If I however remove the formula, set the visible to True, , and then use that formula again, it does seem to work. It however does not stick as when I exit the app and come back in, its broken again. 

@_Corey_ , Microsoft, why is this issue (which will have serious effects for a lot of customers) not on your Powerapps service health dashboard here: https://powerapps.microsoft.com/en-us/support/ ? 

Why do we need to come look through community forums when you're well aware of the problem?

Final update: A hotfix to address the issue has been successfully deployed. The updated Studio version is v3.19052.20.115177617. You will need to edit your app(s) in Studio and re-publish for the fix to take effect--please remember that it make take up to a few minutes for the newly published app(s) to be packaged and available to players (web or mobile). Please report any issues you experience with this update.

Once again, we are sorry for any inconvenience this has caused.

@Fox I'm not sure why the PowerApps Service Health Dashboard was not updated.  I will follow-up internally on this.

Thanks. I can see it is fixed now.
