We see the same things happen with adobe, excel and others.
I fixed it by letting the user logout. Then remove the rights to the apps and let the user login. Then,after login, again logout and then reassign the apps to the user.
Then let him login again and it works as it should.
A takes a little time to do it, but it fixes the problem
