I performed a password-encrypted iPhone backup to iTunes on my Mac and then erased all content and settings on the iPhone. When I restored the iPhone from the backup, all sleep analysis was missing from the Pillow app. The sleep data recorded by Pillow is in Health, but not in Pillow - even though the app has permission to read and write Health data. Has anyone else experienced something like this? It's just a few weeks of data, but it's super annoying to lose the analysis. Edit: re-paired Watch and restored backup.
