Have you broken the API authentication process along with the new update that was pushed today? It seems authentication is not working now. New page asks for client ID and nothing happens when i click continue button. Also recaptcha returns error "ERROR for site owner: Invalid domain for site key" on the same page. Click on forget Client ID and see for yourself.
From July 2021, i was using the same process on V1 and later migrated to V2 around 3 months ago. It was working fine till friday and now its broken.
