Timer goes for ages then tells me to check internet connection.

I have Internet connection working fine for everything else except restaurant story 2 which I also play.

I'm on iOS 9.3.4 which should be supported and was working fine just a few hours ago. No updates available.

I don't see any maintenance planned, have turned phone on and off and closed game etc.

Reluctant to uninstall/reinstall as had problems with this in the past and I can't remember my log in info (how do I check that?)

Hopefully resolved soon.
