I recently bought my Fitbit in December last year (iPhone user). Since then it’s been nothing but issues with data sync between the device and app. All my sleep data is wrong. I woke up at 6am this morning and it said I did at 11:30. Workout data is wrong as well. The times and zones are wildly inaccurate when it’s synced to the app. It’s not a one-off. These happen every day. I don’t know if it’s a Google/Apple issue but this device is by far the worst fitness tracker I’ve ever used.
