Large PowerApp not opening for editing



I have been working on an app for a few weeks. It is very large as it has quite a few pages that use the same form in different ways. That said it has not changed significantly in size (or in any other way) for a few weeks.


I have been opening it almost daily for editing. Although it takes a while to load, load it did.


I last edited on 6 Dec as since then I have been looking at other jobs and associated apps in the project.


This morning:


1. I played the App for testing. It opened and worked OK.


2. When I opened it for editing it loaded for a relatively short time and just opened as a blank app (that is, if I cah hit create app rather than open app)

3. I tried the following:

- reverted to an earlier version.

- I had been always opening (in a dedicated account) in an incognito chrome window. Tried in Edge instead.

- Rebooted Workstation.

- Shared for editing with my eberyday account and tried editing through that.

- Fired up a spare workstation and tried on that (Chrome and Edge).
- Cleared the Cace


None of these made any difference.


I have to conclude that some change has been made in the background by Microsoft. 


Has anyone else come across this (I could not find an identical issue when searching the forum).

Is there anything else I can try?

Is there a fix for this?


Many thanks in advance,


Andy Chisholm
