Backup to OneDrive

I read other OneDrive issues, tried different browser,

activate the toggle on backup to cloud.

I’m taken to MS office online page “Which account do you want to use?” where it asks me to sign in to my office account.

I sign in okay. I see my App Permissions and BackupGuard is in there.

It’s not getting a response from here: https://backup-guard.com/onedrive/&response_type=code&scope=files.readwrite%20offline_access&state=
