Fitbit Versa 3 not tracking HR correctly on Elliptical and Bike

[cardioqueen21]

My Versa 3 seems to track my HR accurately when I use the treadmill or go running (up to ~150/160 bpm). It also tracks pretty accurately on one particular elliptical machine (130/140 bpm), but I recently switched gyms and my HR is not going above 110 bpm even when I am working out at high intensity. 

My Versa 3 has never tracked accurately when biking outside or using a stationary bike. 

I used to have a Charge 2 which tracked higher heart rates while biking/exercise biking, but since switching to the Versa 3 my HR doesn't go above ~110 bpm. 

Any ideas on how to resolve this issue?

I have the similar problem. My HR go up at the start of exercise, but after some minutes falling down from apron 130-150 quickly to 80-90. Here ist it whole time of exercise (ca 30 minutes) and then by calm down break up to 120. I tried get the wristband tighter and also looser, but without effect. Before I used 6 years the Blaze and I know that by my rowing exercise was full time between 135-160 bpm. Versa 3 was a upgrade from my old Blaze, but I'm very excited by this. I'm afraid what were come by running exercise.
