Swimming heart rate on Versa 4 sporadically

[Pdadams4]

My versa 4 does not always record my heart rate while swimming. Sometimes it does, other times  there is a gap in heart rate while I am swimming

Interesting. No Fitbit tracks HR during swimming. When I track swimming I see no HR at all. How do you track swimming? With Exercise app or relying on autodetection?

My fitbit 4 was great tracking my heartrate while swimming. My versa 4 does
sometimes.

Exercise app

That is weird. Officially, HR is disabled during swimming and on my Sense 4 I don't get it at all.

Yes, I get it. I'm saying you should not get HR when swimming. All Fitbits disable HR tracking when swimming. Can you post screenshot from the Fitbit app with the Swim activity that captured HR? I'm curious.

I think there is a duplicate there, but these are some that recorded HR. I
usually swim about 7:30 - 9a
