A friend of mine downloaded the game a while ago at work and played up to level 7. Unbeknown to me she stopped playing because she couldn't get neighbours so deleted game. She's trying to re-download but no luck. It keeps saying she needs internet connection which she has. She's tried switching off phone, she has both her mobile data to download and home connection, there are two versions to download, I've suggested one may be a valentines version so not to try that one.
Are there other things my friend can try?
Addition: I've just found out the other version is the winter version and I know iOS isn't playing that version either. Is android currently using Valentines or winter and if so which one is guaranteed to work as my friend tried both versions too but no luck.
