I share the iPad app with my wife and I notice that there seems to be some caching going on. Whether credentials or data I can't say, but if I log in to my account, log out, then my wife logs in it still shows my data - all of it, in every section, even sections I didn't view - even though the app claims to be loading data and I can see network activity happening. Similarly, if she logs in first it will always show her data. The only fix seems to be to log out, force close the app, then log in. This is a bit of a pain, please fix this so that logging out is actually logging out.
