I started seeing this error message today whenever I open Google Keep. It reads, "Access to Keep is unauthorised".
So I have archived my notes and taken a screenshot to post here.
Can't find anything about this on Google. Any idea what this is?
OnePlus One, latest stock ROM, COS13, non-root. All apps updated to latest versions​.
And this issue seems to extend to the Google Keep web app also. Its says, "You’ve been signed out. Please reload the page to sign in again and continue working."
UPDATE
I no longer see the error message. It resolved somehow, and it's probably due to some work done from Google's server side.
