Power App can be played/ran but not edited

Posted on by DrSicoco

I have inherited a Power App which is I am able to "play" and use as a normal user but cannot Edit under make.powerapps.com. The editor just hangs at "Loading" with the spinning wheel and the editing tools never actually load, much less the screens or data.

The Power App has a connection to an on-prem SQL Server via a gateway and can be "used" just fine, but editing will not work. I have of course, tried clearing the browser's cache, tried Chrome and Edge in private modes, not in private modes, tried another laptop and even loading from my hotspot. Nothing works.

How can I even diagnosis this or look for logs or any hints. Just "Loading" and a spinning circle ain't so helpful. Eventually the browser tab will report "Not Responding" and I can wait or close it. Waiting does nothing. Any thoughts, team?

Thanks in advance!

Hi @DrSicoco,

Great start with clearing cache. Try these as well.

- Revert to a previous version,
-Check data source,
-Disable Preload App for Enhanced Performance (in settings).

The app unfortunately a mission critical production app, thus I cannot revert it to a previous version, especially considering that it "works" in the sense that one can use it and the data still lands in the SQL DB.

I see nothing wrong with the connection to the SQL DB or the gateway. Again the data entered into the app lands in the correct tables in the SQL DB.

I cannot edit any settings, as I cannot edit the app.

Is there no diagnostics or logs or backend something so I can at least understand why it won't load in editing mode?

One way to view errors down to individual sessions in a canvas app is with Azure Application Insights.

You would need to create your app instance in Azure Portal and add your instrumentation key to your canvas app.
Azure App Insights For Power Apps - Power CAT Live (youtube.com)

Analyze system-generated logs using Application Insights - Power Apps | Microsoft Learn

For load times, you could also run Microsoft Azure Monitor.

I hope this helps.
