Im starting to lose chunks of my heart rate data throughout the day again. Overnight from about 4am until I actually woke up around 6am (causing bad sleep & HRV data). Then again this evening from around 6pm till 7pm HR was missing. Throughout the day it was fine, yesterday was absolutely fine too, there have been no changes to the way I’m wearing the watch.
For the last couple of weeks it’s been fine, went on to 12.27 beta and all was still ok but today it’s started playing up again.
