Anyone have any ideas to update? I've tried manually with the latest beta this doesn't work when you disconnect the watch.
So the watch is stuck on 5.70 - also tried factory reset.
Yours must be an APAC version. The latest firmware for the APAC version is sadly 5.70 - which is 5.50 + Pulse Ox enabled in Japan
i got it via amazon last year must have been from third party seller, this is rubbish :(
