Negative Altimeter
After a recent watchOS update (7.2) on my series 6 the altimeter complication is showing a negative value (-1,130FT) previously showed 913FT.

I've had an unreliable altimeter (barometric) pretty much since I got the Series 6. It indicates about 2100 feet too high most of the time.
If I un-pair and re-pair the watch, it shows good altitude for about a day, then climbs 2000+ feet.
When I installed watchOS 7.2, it corrected the problem for one day, then high indication again.
In the elevation field of the Compass App, the error is maxed out at +/- 1650ft.
The altimeter actually works and it is very sensitive. I can raise and lower my wrist and see the altitude value change. It's just that the calibration is way off.
Talking to Apple via text chat and phone has been a huge frustration.
