UI second beta blood oxygen problem

[usermkctxa3xCZ]

Since installation of the second watch 5 UI beta version, Samsung health sleep reports no sleep blood oxygen levels. In addition, manual blood oxygen level measurement seems to give 99 to 100 percent readings consistently when previous levels were always lower. An observation, blood oxygen is successfully measured no matter what position my arm is. Previously positioning my arm was critical, resulting in position instructions.

@usermkctxa3xCZ You should always post comments about the Beta in the Beta discussion area. This ensures that the correct people see it. 

Have you verified that measuring blood oxygen during sleep is still enabled?

How do I assure I am in beta area? I did check and measure blood oxygen is still enabled. I also tried toggle and failure still occurred.
