Apple Fitness + fails to sync libraries on Apple multiple devices

by Poster May 5, 2025 6

The apple id in the national area is matched with the apple one car, and the store in the US area, music, tv, etc. can all be synchronized normally, but fitness + can't At present, the fitness database, fitness plan, etc. only exist on my iphone, and at the same time, another iphone, ipad, and apple tv can use fitness but it seems to be an independent account (after looking at it, they are actually all US accounts but the data is not synchronized), there is no synchronization database at all, so that it is now impossible to use apple watch to connect to apple tv for exercise (because the database in tv is empty and out of sync) All devices have national IDs and US stores, and all devices' fitness accounts are logged in with the same id, the system is the latest version, and the health data in icloud is also synchronized, but fitness + doesn't work (in another similar post I saw someone post that a colleague has a separate icloud synchronization option for a fitness app, but I don't. I don't know if it's a bug from me or if the latest system is integrated into the health app) Any heroes who have the same situation or know how to solve it? Ask for help.

I remember this problem seemed to have occurred before, and then I got better (I searched reddit casually and several people said similar https://www.reddit.com/r/AppleFitnessPlus/comments/1ah9hkk/custom _ plans _ not _ syncing _ across _ devices/) I have encountered other health data synchronization problems before, probably twice (both should be in 201X), and the final solution was: Backup-> Reset-> Restore Backup

@ Anonymous2159 I've also seen more than one person in reddit and apple's own support community with this problem, but there's just no solution

Similar problem I seem to solve by logging back into iCloud through the device

Is @ Anonymous4867 primary device relogin or full device?

@ Poster I don't remember much about this. The situation I encountered at that time was that I wanted to use Watch to link Apple TV sports, but the pairing was unsuccessful. I remember that I have re-logged in to iCloud on both iPhone and Apple TV.

I also have this problem. The data between the mobile phone and the pad is not synchronized at all. 😂
