The Oreo 8.0.0 update went through to my HTC 10 yesterday, and since then I have been continuously prompted to take action on my Google accounts. When I go to do just that (as in: sign into my main Google account and others), it tells me I've been logged out and I need to sign in again. If I click "sign in", I am taken to a screen where I can enter my password. When I do, I am cycled back to the screen that tells me I have been logged out and must sign in. I have done this countless times through my phone after several reboots, to no avail. My accounts have not been hacked, as I can log into them from my PC - I just can't get into them from my phone. This has prevented me from updating my apps via the Google Store. It also keeps me from using other Google services like my accounts on YouTube. I have an independent email app for a non-google email account and I have been prevented from accessing that account, as well. What should I do?
I have run out of ideas. Your help is very much appreciated.
