Cannot add https://connect.wpmailsmtp.com/google/

Replies: 0

When creating the credentials in GCP for this plug in, I’m unable to add this string

https://connect.wpmailsmtp.com/google/

into the URI. The modal complains with the following error…

Invalid Origin: URIs must not contain a path or end with “/”.

If I remove the last “/” in the page and enter only https://connect.wpmailsmtp.com/google

then I get the following message when I authorize the plug in.

Error 400: redirect_uri_mismatch
You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy. If you're the app developer, register the redirect URI in the Google Cloud Console.

… Please advise, and thanks for your support!
