Connect button is not working ? nothing appears ?? Here is the solution.
I've seen many people who has this issue, When you tap on the connect button for syncing your game nothing happens. I had the same problem and been looking for it for a long time and finally realized its not supercell's fault. The problem happend when i updated my Google play games and it was the main problem. Anyways, if you can rollback the update thats no problem and if you can't, download this file:

If the problem was still remains, rollback your google play service as well, here is the apk link:

I don't know what's your device API but they are my default. Hope this can solve your problem :D let me know if it worked.
