My wearable isn't syncing — what should I check?

First, open the wearable's own app (Oura, Whoop, Garmin, etc.) and confirm it has synced recently — Nutreaze can only read data that's already made it into Apple Health or the source's own cloud account. If the wearable's own app shows stale data, that's the actual problem, and reconnecting there (not in Nutreaze) is the fix. Next, check Settings → Connected Sources in Nutreaze and confirm the connection still shows as Active; permissions can occasionally get revoked by an OS update, especially after upgrading iOS or the wearable's own app. If it shows as disconnected, tap it and reauthorize. If it still isn't syncing after a few minutes with both of those confirmed, disconnect and reconnect that source from the same screen — this resets the sync token without affecting any data already stored. Still stuck after that? Contact support with the specific device model and roughly when syncing last worked normally — that's usually enough for us to spot what changed.
