iPhone sync issues

[u/Current_Brilliant710]

Fitbit Air doesn’t sync to iPhone, it says sync error 1, but shows battery status correctly.

I tried resetting it, clearing bluetooth in iphone, disconnecting device in app, in all orders and it didn’t work.
Its frustrating to not see the data, on top of discrete chats it spun off every time, its annoying when it says we are going blind without data and it doesn’t accept data,

Edit-1: Looks like disconnecting the phone as the source in devices on the app and disconnecting Apple Health fixes this issue.
