Unable to get it to work after 2 months

Unfortunately even after app updates and Garmin updates as well as installing beta, the app is still not collecting oxygen readings from Garmin Vivoactive 4. It drains watch battery and there is no data to show. Otherwise Garmin Connect app collects oxygen readings very well and I can track my sleep no problem.

As this was one of the key features that I need, I have to request a refund.
