I’ve successfully tied together Zeppelin and Sonar, but it doesn’t seem to be bringing most data over. After syncing them together two days ago, all I can see is some partial sleep data, and resting heart rate data, everything else like Steps, HRV (my main want), etc doesn’t seem to be coming over. iPhone 15 Pro Max iOS 26.2 Amazfit Helios Strap + Zepp Apple Watch Ultra 3 with Apple Health (eventually, when Zepp sync is figured out)
