Fitbit Versa 2 swim tracking inconsistent with length

[Aquaman83]

Hi, i am a first time fitbit user. My concern is i timed myself on a 50 metres lap pool with the swim tracking app. I done 20 laps which would be 1km in 26 mins. After syncing with the fitbit app, report shown that i have done 550m. All other previous tracking seems to report lesser length covered. Why is that? Is it because this watch is so bad?

I have also been reading and found out that the funtionality for detecting length and laps straight from the watch that was avaiable in previous model has been removed!

I'm not aware of laps being removed. Lap timers have been removed. 

Have you setup the pool leangth?

Not sure what else can be done with regards to the swim tracking.
