I have an annoying bug that started to appear a few weeks ago (looks like 09/24) where most of my all-day heart rate is not available on connect (web & app similarly) - only a flat line appears, see the screenshot for an example. Heart rate was recorded for these time periods, as a matter of fact the run visible in the screenshot had normal heart rate, that correctly appears on the corresponding activity page (meaning it was synchronized by the watch). Also, the all-day stress appears normally.
Any idea what might be wrong, and how to correct it? I basically have no heart rate data available anymore, which is a bit annoying...
Thanks a lot!
(PS in case it matters: Fenix 5S).
