Anyone else having an issue with GCC where the app is getting hungup on the loading screen? I have no onStart commands but all of a sudden others using the app are getting hung up on the part where permissions are usually asked. I am using SharePoint and Office365Users and not even a minimum viable powerapp is working; it just hangs.
I've made a similar test but not met the same problem like your description.
Did you try other browsers?
Please try to clean your browser's cache , update browser to the latest version, try other browsers and try again.
What's more , please check whether your firewall/popup blocked PowerApps.
Please note that:
LoadData() is not supported in WebPlayer and there is a known issue that we are trying to address where if you use LoadData in 'OnStart' it hangs in the webPlayer. Workaround would be to not use it until we fix the issue.
