Hi everyone,

I'm encountering an issue with the PowerApps editor. Whenever I try to open the app for editing, it gets stuck on the loading screen, displaying a spinner as shown in the screenshot below:

PowerApps Editor Stuck on Loading Screen

I am having the same issue. Also only with our org's largest canvas app (>20 data connections). In the rare event the app does load in the editor (after several hours of waiting), it is completely locked for editing, and is just buggy and unworkable in general.

We have tried several troubleshooting steps on our end. This is 100% a new issue on the MS side.

Please help.

UPDATE: I found a helpful Reddit comment that fixed my issue with this!
Wait out the "Loading..." message. Mine took several hours to get past, so just be patient. If you do ever get into the editor, its still going to be a laggy unworkable mess, so...
Go to your app settings and turn on the "New analysis engine". NOTE: There was a pop-up, but no visual confirmation for >1hr when I toggled this setting. Again, be patient.
After you've confirmed that the new setting has toggled to ON, save and reload the app.
From my experience, the editor is still quite slow compared to it's state 1mo ago. But at least I can get into my app and make changes in a timely fashion again.

Having this same issue as well, and have been for the last couple days. Only happens on one of my apps, of which happens to be my largest/most complex.

Sometimes when it did work (as in load the editor), I was unable to actually edit the app. The App checker would spin indefinitely. Something is definitely broken on the MSFT side, not sure what is happening. Hopefully It will be fixed soon

@Velegandla
On Developer tools (F12), it displays this error,
https://*******.59.tenant.api.powerplatform.com/powerapps/userSettings/modernLeftNavToolbox_prod?api-version=1
I'm not familiar with this error.
I have tried the other option as well, it isn't related with that. Here I was trying to restore to its previous version, sometimes it open the page but when I refresh it(to make sure) , still the issue persists.

@Mikias23

I suspect, issue could because of internal company network.

Can you check Developer tools (F12). Does it show any error?

Is it happening only in your machine or other machines as well?
