Hi Everyone,
One of our users has recently been having issues accessing each of our PowerApps hosted on our SharePoint Online Site. We've been receiving the error "This app isn't working, refresh your browser or try again later" and under more details, we've gotten the message unknown user.
I've tried refreshing the browser, clearing the cache, trying an alternative browser, signing out of the account and signing back in again, but unfortunately to no effect. The apps have been working fine for myself and other users on our own accounts and PCs, but when I logged in using my own account to test on the machine of the person receiving the error, it had stopped working, this would lead me to believe the issue may be specific to the user's PC. I've checked permissions within both SharePoint and PowerApps, and all seems to be correct.
Apologies, I'm still very new to both PowerApps and SharePoint and would appreciate any help.
Thanks very much!
