HI,
I have an app where users need to complete an additional questions before the process is complete.
I have two users who cannot see their forms to be completed. 100's of user work as expected.

SortByColumns(Filter('Clinical Supervision',Email = User().Email, Status = Blank()),"ID",SortOrder.Descending)
A link is received via email once the initial conversation has been had with them to this above form.
They users will only be able to view their un-completed forms. For two users they are unable to see any information for them.
I've checked AD and the emails in the SP list match the Email in AD.
Does "User().Email" actually relate to the Email or does it use the UPN from AD??
