A user of our add-on reported as follows and I was able to reproduce the issue
The user got an error saying it is partially installed and it needs to reinstall the app.
- uninstalled and tried to install again the add-on and got this error message
"Sign in with Google temporarily disabled for this app
This app has not been verified yet by Google in order to use Google Sign In."
- see screenshot below

I checked in GSM an the add-on is public, published and verified as it has been for a long time

Is this a side effect of the GSM migration or I am missing something important?
Anybody having a similar issue?
Thanks
