“Browse backup” shows 70 contacts are backed up, while “Backup Items” says 71 found, 71 done. So the app does not compare items it think was backed up with items on server. I think it should do this, because now there is no option to backup one missing contact on server, which for eg. was deleted by my mistake and is present on my device. The only thing to fix it is to delete everything in my.avast.com and Google Drive, clear Mobile Backup settings in Android’s app manager and to go with fresh start. I do not think it is the way it should work >:( After what it compares information with info on server and shows correct status - missing contact on server was detected.
