I have noticed that with 17.3 beta that while my iPhone 15 Pro indicates I'm connected to wifi that I still have a ton of cellular data usage. When I'm not connected to wifi using facebook to open a webpage or safari and many apps I receive a message about unable to reach server or network not available - while some things X/Facebook work for the normal feed. Somethings not right in 17.3 beta....

updated to watch os 10.2 (21S5331f) and have the same issue. i changed the complications arrangements and the Blood Oxygen icon does not show on the actual watch face regardless of where I place it. So it would appear to be an issue with just that icon.
