Black screen in powerapps PC app version - all computers

[cloudsurfing]

Has anyone come across an issue in the last few days where the PC version of Powerapps only shows a black screen when starting any power app?  Our apps are working fine on android but the PC app only shows a black screen after selecting / starting the app.  This is happening on all of our PC's so its not a single computer issue. It has only started in the last few days.

Would really appreciate any insight that anyone has about this.

Thanks.

Logged a support call.  Looks like its an issue with latest Authoring version.  Going back to 3.21093.33 will solve the issue in the meantime while they fix it.

I have the same issue, but don't know how to fix. How can i go back to previous version of powerapps (3.21093.33) but still publish my new changes to the app?  btw Black screen issue is only on IOS and windows app. Browser and Android are working fine.

When you are editing your app, you go to settings and then support option as per screen shot below.  In this section you can manually revert the authoring version of the app.  This is nothing to do with the actual versions of your app, it is more the platform version.  When Microsoft updates the entire platform, your authoring version is automatically updated next time you open the app to edit it.  Apparently it is recommended by MS to republish your app regularly even if you havent changed it so that you get the benefit of any new platform updates.  So all you need to do is rollback the authoring version and then save and republish your app and then it will work fine again in papps desktop.  When MS release a fix it will be a new authoring version and next time you edit your app it will automatically be updated.  This is what I was told by MS support anyway.  Hope that helps!
