Not earning floor badges with Pixel Watch. There are some months old threads saying this is a known issue, but no apparent resolution.
Not only are badges not showing as earned, but I have no floors showing in my lifetime achievements.
This issue still has not been resolved. This was considered "high priority" when I opened a ticket in January. I haven't received a response since. Take that for what you will..
I'm guessing developer time is being taken up by removing features and crippling the user experience, in turn making it exceedingly difficult to care about or fix existing problems.
