Okay so basically I downloaded Twitter on the mac app store on account A. In the updates tab there is an update for version 2.1.1. I download the update, close the app store, open it again, and the update is still there! I recently made another account, we'll call it account B. I haven't made any purchases on B yet but the twitter update is STILL there and refuses to go away. When I click install it says I have to log into account A to install it (which doesn't work). HELP PLEASE
