Have been spending weeks with support. Most advice is reset watch app etc Exercise gets mapped but gps not measuring kms then next hr works fine. Sleep recorded 3 hrs after I’ve been to sleep BP machine doesn’t always record on app despite being next to ph app open etc works 95% 0f time Faults in app told will be fixed next update but unable to give date of update Love it when working but too erratic unreliable makes me wonder how reliable is the scan watch also I honestly would not rec one day this app with devices
