Migrate Your Google Forms to Microsoft Forms in Microsoft 365 Admin Center

Hey tictag, not sure if this is still an issue for you but I was able to access mine after I went into SharePoint admin and  - under user profiles- manage user profiles- search for your test user,  -and manage site collections owner and add yourself (or admin account you user), that should do the trick and it will show the folders for the user. I hope this helps.
