Jdsteiner , via OnePlus 8 Pro , Apr 19, 2021 : SpO2 Tracking and Sleep Data are simply not appearing in my app, despite stress, workouts, and heartbeat data syncing. They track on the watch just fine, but nothing on the phone, so I have no real way of using SpO2 or reviewing sleep data. This is very disappointing, is there a trick to get it to work? Or do I need to return and wait? Edit: I've been reached out to via the google play store, but let's be honest, last time Oneplus told me they'd fix something, well, my 8 Pro still has black crush and green screen. This might be the last nail in the coffin for me, and I've been a customer since the Oneplus 2.
