I had a security download (but not yet installed) ready yesterday. Logged off without installing. Turned on my device today and couldnt log in. Checked my pwd 3 times before seeing "authentication service not working " iirc.
After reboot it installed and logging in worked.
Is this related or not and is it expected? Not being able to log in without a mandatory patch first so to say?
Thats just a user frontend showing your personal view of things . Nobody outside Google knows for sure if they really remove it from their end. All we know is they COULD keep a copy for themselves.
There is a big difference between posting in public non confidential stuff and an app tracking all your clicks and likes and device contacts and telemetry
