Update fails because App Store *thinks* another account did the purchase
I bought XCode a few weeks ago. Now that there is an update I wanted to update. But whenever I try to update it, I get the following message:
"You have updates available for other accounts.
To update this application, sign in to the account you used to purchase it."
Problem is: I am signed in with that account ! Logging out and back in does not solve the problem, neither does rebooting.
Moreover, when I check that account it indeed shows that I bought XCode with that account.
Somehow XCode (but not other applications I bought like FaceTime) seems to think it is registered to another account and hence does not want to update, so I'm stuck.
Help !
