Re: Had to change google password, now phone says "There was a problem communicating with Google"
This is correct, except that when you use 2-step verification on the Google account, you need to enter an application-specific password when re-creating the google account on the phone. Then it will work even with 2 step (I have seen many other posts on this on various forums where the solution was reported to be turning osff 2-step, but that is not necessary if you set an app-specific password for the google account on the phone).
Go into settings>general>accounts>Google and then choose your Google account. You will see an option at the bottom right to remove the account. Then you need to add the Google account back with your new password
