On the Pixel Watch user also try to sync sleep and heart rate via Fitbit so they are unable to do that. If talk about the stats or record, when the app opens data not showing and not in the feed also.
User data like steps count, distance, active minutes, heart rate, calories, and more are not showing because of this issue. This is maybe because of some bug or issue and after resolving this data on Fptybit will save in the device. Fitbit’s server was down partially for around three hours.
Lastly, the company surely working on this and provide some solutions and users will use Fitbit as before.
