This app isn’t verified

Hi,

I’ve been using Backup WD (to Google Drive) on several projects and worked great.

Recently added this plugin to a new project, and setup google drive api as normal, copied the clientid/secret id to backup WD configuration.

When trying to reauthenticate backup job, i keep getting :-

This app isn’t verified

This app hasn’t been verified by Google yet. Only proceed if you know and trust the developer.

and if i got to advance, and continue via unsafe i get 404 page.

Please can anyone direct me into why this is happening.

Thanks in advance
