PowerApps Studio taking to long to save

[danielfsantos]

Hey,

When I open a canvas app it can take more than an hour to open the selected app. When it finally opens, it is really slow and takes forever to add any changes, to save these changes and to close the app. Is anyone having the same problem? What can I do to overcome this problem?

Update: I get this error multiple times on the console:
DevTools failed to load source map: Could not parse content for https://sourcemaps.powerapps.com/srcmaps/static/js/module/309.bea7be0b.chunk.js.map: Unexpected token < in JSON at position 4
 

Thank you,

Daniel

What is the authoring version of the app?
How complex is the app?

• Connector count
• Screen count
• Performance warnings (especially cross-screen references)

This was an issue a few weeks ago for multiple people. Meaning, the long hangs opening the studio. Basically, it seemed like complicated apps had issues with recursive data calls causing it to hang up before finally initializing.

The app it's using version 3.21101.26 since 2021-10-19. It's using a couple of Azure SQL connectors and has around 20 screens.

Should I revert the app to a previous version of the app? Or there is another solution to this issue?

The long hang opening is a concern. Do you have it open, or could you open it, and make a note of the errors/warnings listed by the app checker. Especially the ones noting cross-screen dependencies.

We didn't have an explicit fix when it happened in some of our apps. Reducing complexity helped, but the highly impacted apps eventually became more manageable.

Additionally, try a save as of the app, and see if the saved version opens any quicker.

I had to revert the app to be able to open it. I have a lot of performance warnings, especially cross-screen that I'm going to focus right now to solve them. 

After the save as of the app, the new app opens quicker than the original.

UPDATE: Even after fixing most of the errors, when I restart the app it keeps getting stuck on the loading screen. The app only opens on edit mode when I revert it to last week version.

I removed all of the performance warnings and the app still takes 20/30 minutes to open. When it opens, it barely moves and I'm not able to change anything.

Update: When I try to turn off the 'Collection access in component scope' and restart the app, the problem seems to appear again. The app takes a lot of time to open.

@danielfsantos did you ever get this resolved?  I am having it now and I don't think that my having say 10 or less screens should be causing the system to HANG for MANY MINUTES even to open / save / etc.

@MLCarter1976 I think I had to create a new app. I didn't have to create everything from scratch, saving as a new app solved it, the only problem that this caused me was that I had to manage and update any link to this app because of the new web link generated. After this, the app started working fine again but I started to improve performance and follow controls recommendation for each screen.

I hope this helps
