I have an Oppo F11 Pro. I recently changed my Google password on my computer and then I logged onto my phone and tried to access the Play Store and comes up with Checking Info... After sitting on that screen for a while, it asks me to choose an account or add a new account. I choose my existing account and it just cycles all over again until asking me again. Sometimes it says there was a problem communicating with the servers and to try again later. My internet does work though so I am not quite sure.
I can access this page in my Google account in settings where it wants to finish signing into to continue.
