So I’ve had the following problem twice now:
I left my iPod at the play online window - put it away and later (maybe hour or something) when I picked it up and opened it again, it said my friends did not respond yet. Evern after ‘Refreshing’ it said the same. After I went back a window (with the blue go-back button) and pressed Play online it kept saying That I had internet connection problems (which I obviously did not have, internet and all worked).
After I forced-closed the app, restarted it it all worked again.
No idea where this comes from, thought I should report it.
