I’ve seen multiple posts on Google Credentials stop working after a while.
Mostly, the issue is when the Google client is in the “testing” mode.
Therefore, I put mine to “Production” mode and it seemed like the issue was solved… until yesterday when it stopped working again.
What could be the issue here and how can I solve it?
(I shared the concern here as well, but decided to post new topic to bring attention)
What is the error message (if any)?
