new LT detected but zones refuse to update on Garmin Connect, three times now with 28.02

Is anyone else having this problem where the zones on Garmin Connect do not auto-update like they used to?

I've had a new LT detected three times now under 28.02 and the Fenix6 auto-sets the new zones properly on the watch but never syncs with Garmin Connect

both bluetooth updates and direct connect via USB with windows

What's really interesting is the LT history report DOES show the new LT detection

But the zones never update

Physio True-UP is enabled

So Garmin broke it again and is not fixing it? It's been weeks.

Maybe it's a firmware problem with v28
