Similar issue that needs clear direction:
I have 10 devices that we setup with avast! Mobile Backup and provided our Google Drive login credentials.
These credentials have since changed, and avast! Mobile Backup can no longer connect.
The device tells me to go to my.avast.com and disable/enable Google Drive to fix this.
The website tells me: "Before you can disable Google Drive storage, you have to uncheck all your backup settings on all your devices!"
What do you mean by 'uncheck all your backup settings on all your devices'??
Why can't we simply provide new login credentials??
Thanks for the help!
