I have a user that until yesterday could "complete" the sprint, but now the button is greyed out and the tooltip claim that he is lacking permissions.
As far as I can see, he has all the required permissions, despite me rummaging around with all the possible permission he still can't click on the button.
Funnily enough, *I* can access that button but apparently even if I give him all the permissions I have, he still can't.
Any idea?
