I upgraded to a F7 Solar from a F6Pro and I discovered that although the native SMO2 datafield works OK and shows realtime values (from my Humon Hex SMO2 sensor) the resulting workout shown on the phone and web doesn't graph the SMO2 readings like the F6Pro did.
I've not tried this for a while, so I'm not sure whether it's an issue specific to the F7 or whether something broke on the backend of Connect.
Anyone else using an SMO2 sensor with any Garmin watch type successfully?
(NB. this is SMO2 from an external sensor, not the (SPO2) PulseOx readings the watch gives)
