Things my iPad tells me, that my phone doesn’t.

Oh, that pesky “has chosen not to receive messages” note is maddening, isn’t it? I’ve had exactly the same thing: perfectly fine on my phone, then suddenly on the iPad it tells me someone’s closed their PM door. I’m told it’s because the privacy setting is stored per device/browser – a bit of a Gransnet quirk. If you log out completely on the iPad (Settings > Log out), clear the safari cookies, then log back in, it usually sorts itself and shows the proper message straight away. Works for me every time!
Hope that does the trick for you.
