Constant error in iOS 14, doesn’t work – Prime Sleep Recorder Pro Review

The app flashes “no one is logged in to iCloud” or something to that effect. I thought perhaps it was because they were pushing recorder “Prime” & tried that, to no avail, my purchase wouldn’t transfer. So this is now a broken product for this system & still on the App Store. Very disappointing.
