CMAltimeter stops delivering updates for a while then resumes

On Apple Watch (reported several times, but also on a powerful Ultra3), the CMAltimeter occasionally stops delivering updates for a while (a couple of minutes) then resumes.

This makes for a terrible user experience.

  • What could cause this?
  • Is there a way to (best case) prevent this, or (workaround) detect it?

This is production critical, any help would be greatly appreciated.

Thanks a lot!
