Lost my call history and SMS messages after system reset, even though I have a Google One subscription, had backups enabled, had plenty of free space, and even forced a Google One backup shortly before the reset. After the reset, there was no history of any backups from my phone. Reached out to an "expert" who walked me through the various drive/backup settings screens noting I had no backups, and suggesting I contact my phone manufacturer's support. Seriously Google, you can't tell me what happened to a backup I made a mere hour ago?
