Unexpected LoadScreen

Posted on by Kubo

Hello,

I'm baffled by this strange behavior of my app. Here is whats happening:

I load the app and navigate to screen 2
When I try to navigate to screen 3, app goes by itself back to the main screen
This happens only once, when I repeat and try to navigate to screen 2 and than screen 3, everything works until I reload the app. Than the issue happens again, one time only.

Formula is simple "Navigate" function, there is nothing else going on.

I have tried to disable all preview features but that did not help. When I run the monitor, this is what I get:

This is not user action and its not called from any formula. Wold anybody know what is going on here? Thank you in advance.

Edit: This happens only in the published app, not in the editor.

After further tests, it seems that app is resetting when navigating between two specific screens and goes back to main screen. This is not easy to troubleshoot as it is happening only in the published app. Could this be happening due to too many controls on the screens? It seems to stop if I remove enough controls.

I am experiencing the exact same thing. Sadly I don't have any answers.

Same as you I'm experiencing:
Issue doesn't occur when editing app, only in the published version.
No warning/errors visible. In the Monitor, the only thing it says is LoadScreen (MyappsHomeScreenName).
Only occurs one time when the app is opened, will not repeat behavior until it's opened again.
Occurs when leaving a particular screen, whether through the back action, or the navigate action.
App has been around for a long time, this issue only recently started (maybe 1-2 weeks ago).
This app was built a few years ago, and is using the OnStart activity that is now discouraged. Though it's not Navigating onstart, the default screen is at the top of the tree.

I'm using onstart property also including conditional navigate. I have removed it before as a test and it did not help but I will try again tomorrow and let you know.

I have been trying to resolve this for last two weeks but don't have any better answers. It seems to be connected to rich editor when its hidden but I'm not 100% sure. I have seen some post on reddit mentioning the same. It is probably a bug. I was able to limit this to only one screen now so I guess I will have to live it for little bit until someone will find the solution.

Here is the Reddit thread: https://www.reddit.com/r/PowerApps/comments/u1z7nr/powerapp_issues/
