Same for me, nothing showing since Saturday. The device is tracking my Sp02 because it shows in sleep data and on watch faces that support it. Just nothing in the Health Metrics part of the app.
Mine is fairly reliable, except always 1 day behind. My wife an SPO2 reading about 1 day in 4. Completely useless. Tried everything suggested in the MANY threads about the problem but no cigar.
