iOS 15.1 iPhone Storage Almost Full
Just updated iOS to 15.1 and am now getting the 'iPhone Storage Almost Full' message and badge in Settings. First tap clears the badge and message, but then returns. Second tap takes me to a screen to optimize storage by offloading photos to iCloud. Tapping 'Not Now' clears message and badge...but then it reappears later. Storage shows 36 GB used out of 64.
I've restarted the phone multiple times but nothing changes.
