We had an "admin" who has left the company. A user requested access to the project before he left but this was not granted by this admin in time.
However I have admin rights , and have added this user to the project. However, when the user tries to log in the user still gets the "you have already request access" window.
As we are on the "free" product plan, of course everyone is admin and should have full access anyway so it is hard to understand why this user is stuck and unable to login.
