Since around today, March 10, 2021 and recent update to 89.0.4389.82 Chromium stopped syncing to Google accounts. As is turns out, this is due to some changes made by Google.
What can we as users do?

Just came across this solution: gist.github.com/cvan/44a6d60457b20133191bd7b104f9dcc4
Subscribe to mailing list (as stated in gist 1). Then you just enable Chrome Sync API at console.cloud.google.com/apis/library/chromesync.googleapis.com
Now create all the GOOGLE_API_KEY GOOGLE_DEFAULT_CLIENT_ID GOOGLE_DEFAULT_CLIENT_SECRET keys as shown above. I used TV-and-Limited-Input-devices when Creating OAuth client ID. Not sure that matters
In ubuntu edit file: /etc/chromium-browser/default Add lines:
##all these are random numbers from a cat typing my keyboard so please do try them in production if you have free time...
GOOGLE_API_KEY=AIzazUdJiNwlR6zYtNd
GOOGLE_DEFAULT_CLIENT_ID=83728372837-wn4AKjPv02YM1x4gv.apps.googleusercontent.com
GOOGLE_DEFAULT_CLIENT_SECRET=EERRN-JtEoGYoqL7xGZ6hhIxbM
export GOOGLE_API_KEY
export GOOGLE_DEFAULT_CLIENT_ID
export GOOGLE_DEFAULT_CLIENT_SECRET
