Not Sync and Restore – Pillow: Sleep Tracker Review

Since lasted updates is getting worst, the app doesn't sync with Health and I deleted and reinstalled the app to try sync, and It was worst, because I can't restore the data of years. I tried to contact the developer, but it was a standard answer, say they are working on the issue (this was 2 months ago).
