I have the same problem but since about 2 weeks.

It's been more than 2 weeks now. Is there a problem ?

I'm sick and tired of the message that I have no internet connection. When do I get this message ? Every Friday when I can play for extra credits. I play on different devices and when I get to the next level it updates on all my devices except when it involves Raadselberg or extra hours free playing time.

I have the same problem. All week nog problems, not even with Island, only when I try to play Mystery Mountain when I can get extra credits.
