Sorry for the problem. It seems this happens with accounts where 2 step verification is enabled. More info about this: https://www.blog.google/technology/safety-security/a-simpler-and-safer-future-without-passwords/

There is a way where this can be configured in your Google account: https://myaccount.google.com/lesssecureapps

We got reports from people who use the FolderSync app to automatically upload the DailyRoads files to Google Drive.

This can be an option for people who can’t use Voyager’s built-in upload functionality. But, it will mostly work with photos and protected videos, which are not automatically deleted by Voyager.
