Form Displays Too Small

[kptyh]

Hello. I created a customized form from a Sharepoint list that has been working fine until the other day. I set the display settings to 1185x1600 which was the perfect size, and the form would take up most of the screen for easy viewing and entry. Now, when the form is opened it displays on the right side of the screen (where the list details screen opens) and is extremely small. After reading several posts and the Known Issues list, cleared my cache and reset the display settings, and republished the form multiple times. None of these 'fixes' have resolved the issue.  Is this a Power Apps glitch or is could there be something wrong with the form?

After reading this thread and tried all suggested solutions without any luck, I decided to poke around and tried everything and anythibng. And I think the steps below is a workaround for now until Microsoft fix the issue. 
1. Go to List Settings >  Form Settings
2. Click on See versions and usage

3. Click on Export package and give it a name
4. Extract the zip file.

5. Open the newly extracted folder from the zip file

6. Drill down to Microsoft.PowerApps > apps > xxxxxxxxxxxxxxxxxxx

7. Open up the only xxxxxxxxxxxxxxxxx.json file in VS studio

8. Format the document so it is easy to read.

9. Locate the line "screenWidth" and ensure it has the size you want.

10. Do Ctrl+A to select all and then do the Join line, then save the file. 
11. Copy the file and replace the one in the original zip file. 
12. Go back to the List Settings > Form Settings then select Use the default sharePoint form, click OK

13. Go back to the List Settings > Form settings again, then click on Delete custom form.

14. Go to https://make.powerapps.com/

15. Import the zip file and republish it. 

It has been working for me. Hope it will work for you as well. Let me know if you have any questions.

Before form with sizing issue.

Form after issue is fixed.

Thanks for this. I'll give it a shot if/when I run into this issue again.

Can you explain further what step #10 means? "Do the join line"???

Also, is Visual Studio really needed for this, or would Notepad work?

Hopefully, this short vid will help. If not, let me know.

Notepad will work but it is a little harder than using vs code.

I too had this problem.  The solution for me was to adjust the width of a couple of rectangle objects I had placed on the form.   The rectangle width was a little wider than the width of the form.    Once I changed the width of these objects to match the form width, the problem resolved itself...

Thanks, this was the only thing that worked for me (let's see how long it'll last though)

Anyone found any solution to this?
Have tried the suggestions in the thread. It works if I bring up a new incognito/private browser window. Size of form is correct. Then I just need to hit refresh, and it goes back to small.

I have not tried these steps as the issue has not come up for me again yet. But I saved this post on the topic which I planned to follow next time I see it. I'd be curious if it helps for you -

I was able to resolve an issue similar to what was described here and although not a powerapps issue, I think the solution might apply in both cases. I wrote a short problem solution in Sharepoint forums.
