I've downgraded to 5.10 for now and will wait for the fix from Garmin
So we're now supposed to wait through next beta cycle to get a crucial feature back that used to work before. Nice.
Apparently the issue is IQ related too. Oh well, it's getting colder so I'll just use the strap anyways from now on. Hopefully gets fixed until next summer.
The 'beta' adds one fix and no new features. Just because it's named a beta doesn't mean you are signing up for beta testing. If they called it 5.40 release you'd be happy, right?
