Did you try a proper synchronisation with Garmin Express? And as last resort a hard reset (if soft reset does not work either)

maybe you simply disabled it?

1) From the heart rate widget, hold UP.

2) Select Options > Status > Off.

Hi. Thanks but I’ve checked that and it’s on. The pulse Ox also says the software needs updating??
