I've been getting this message for weeks (perhaps months now?)!
I can't access the store for anything. I can't purchase gold in the cash store, but I also cannot use the gold I already have! I can't purchase power ups or additional moves on levels. It's getting horribly frustrating.
It just says "Store unavailable! Try again". Internet connection is fine, as I can get and send lives to friends, and take part on events. Just the store.
Anyone can help, please?
