Before that, let’s check whether the issue persists in a fresh user profile.
Follow the instructions below:
After you create the new user profile, make sure to enable both Allow Google login buttons on third party sites
and Allow Google login for extensions
as we discussed earlier.
Also, after you set up everything above, I would like you to take a screenshot of the Developer console
. So, open the problematic website → click on Sign in
→ press F12
to open Developer tools
→ click on Console
→ Take a screenshot.
