I have no idea what actually could've caused this. I don't use social networks at all, so there's not even a chance I would've downloaded Twitter, before someone considers that. On top of that, Twitter doesn't even show up in my "Purchases" tab, but it does in my "Updates" for whatever reason. Screenshots below. Updates Tab Purchases Tab At first I was concerned that someone may've somehow logged into my account, but then I realized since Twitter wasn't marked as purchased it couldn't have happened. So I've concluded this must be some sort of glitch. I've restarted MAS but not had it go away. Has anybody else had something similar to this happen to them?
