Dear experts,
I have a Sharepoint form that has been modified in PowerApps.
It has a gallery with three different filtering options, one of them being by logged in user, i.e. Agent=User().FullName.
It has been working just fine for years, but all of a sudden, the User().FullName feature has stopped working for some of my users. The gallery returns empty. It's like the app doesn't recognize who is logged in. Some users are effected, not all! Remaining filtering options remain fine for all users.
My formula does have a delegation warning, but if this is the problem, shouldn't it affect all users?
It's this chunk of the formula:
&&If(Filterbuttons.Selected.Value="Mine";Agent.DisplayName = User().FullName;Agent.DisplayName<>"")
Any ideas, please?
