HR Data became wrong after syncing

This morning, I woke up and sync my garmin to Garmin Connect. I clearly recalled my RHR to be 43. But after I sync a running activity today, my RHR became 49? Also, I don't know how but my max heart rate for today became 197 when clearly I didn't hit numbers in those range any time today?

I thought I was going crazy because my RHR also changed a few times before in the past few weeks. 

Can someone make sense of this?

    Hi, I encountered this issue recently (today morning also ) I have at least 3 hours with low heart rate around 44-45 during sleep time ... my woke up RHR was 47 then after syncing it jumped to 54. Looks like it wasn't taking the sleep hours into account (by definition should be the lowest 30min average) and there is no logic to change it.

    Also recently I see that overall average stress is kind of random... sometimes accounts well the whole day sometimes is very high (as it's taking only the last hour or something into account)

  • Happened to my fenix 7 few times again ... any news about this one ?
