Hi @hotchd,
Thanks for reaching out, and I’m sorry you’re running into this issue.
The error you’re seeing is coming from Google and typically means there’s a problem with the credentials used during the authorization request. To troubleshoot, if you have confirmed all the credentials from your Google app, try signing out of any default Google accounts in your browser by visiting Google.com. Then reconnect using the same account you used to create your Google app (client ID and client secret).
If the issue persists, I recommend reconfiguring the Google/Gmail mailer by following our step-by-step guide.

I understand this can be frustrating, and I appreciate your patience. Please note this limitation is from Google, not WP Mail SMTP.
If you’d like to explore alternative mailers, you can view the full list of Supported Mailers.
Hope this helps and thanks again!
I’m having issues also, I tried deleting the Oauth and readding it and get the following:
Access blocked: wpmailsmtp.com has not completed the Google verification process
wpmailsmtp.com has not completed the Google verification process. The app is currently being tested, and can only be accessed by developer-approved testers. If you think you should have access, contact the developer
