16.28 update caused problems with focus mode, HRV

I updated to 16.28 yesterday, looks good!

Last night, at about 3:30am, I was woken up by my watch when a bunch of notifications came in. I looked at my watch and I wasn't in sleep focus, the Forerunner 970 was full OLED color. That has never happened before. I tried to figure out how to switch it back to sleep focus, and found the focus mode option in the rotary, and when I went there to select 'sleep', it didn't change, and was in 'activity' mode. I gave up, and went back to sleep.

Morning came, and I had no HRV reading, and the watch still thought I was in "activity" focus. Is there something I need to do to get it back to normal focus, and get it to pay attention to my HRV again? 

  • I rebooted the watch, and as soon as I unlocked it, I was presented with my Health Snapshot data from yesterday, asking me if I wanted to save it. Once I saved it, everything worked as it did before.

    Yesterday, I ran a Health Snapshot and when it finished, it never showed me the results, or asked me to save them. I guess it was in a weird state, and once I restarted, everything was back to normal.
