Sensor Hub 0.01 issues, Garmin Forerunner 955 Solar

Hi everyone,

Since an update 2 months ago, I'm having a lot of issues with my Forerunner 955 Solar sensors. Heart rate is often not working at all, or barely working. Same for step and stairs count.
GPS tracking is doing okay.

The watch also contstantly updates itself! Sometimes even twice a day. But I get about 6 to 7 updates a week.

In the 'about the watch' screen in my Garmin Connect app on my Pixel 9 phone, i see:
Sensor Hub: 0.01

Could this be the issue? And ... how can I fix it? Is it fixable? Seems like a software bug.

Any help is much appreciated. This is driving me crazy.

Kind regards,
