Multiple devices

Have been using SaA for sometime together with Skagen-WearOS watch to my satisfaction. A few weeks ago I bought an 02Ring, which works fine standalone.

I tried to integrate with SaA, using the 02Ring add-on yet have only once seen O2 values come through and that time no movement, nor heartrate. Have stopped selecting the O2 in the add-on, yet the heartrate icon in the sleep tracking screen stil mentions my 02 ring. Still think the values are from Watch, just not sure.

Has multiple devices been fixed?
If not prefer just using the smartwatch (given movement in addition to heartrate).
In one of the threads, read a comment that the values of the O2Ring could be included the next day (not sure if that was directly OR via Google Fit.
Can anyone help? Thanks in advance
