Registering peak zone minutes

[Lisa_CN]

Since an update 3-4 weeks ago I have not been registering any minutes in the peak zone even though my max heart rate is above my peak zone bpm - my peak zone starts at 166bpm and my max heart rate has been ~170bpm. I have also noted that my calorie count has also been lower than usual, by approx. 50-100 and I seem to be spending a lot of my workouts in below zones even though I'm sweating buckets! I have reset the watch and am mindful to wear it in the appropriate position. One of the other ladies whom I work out with has the exact same problem and we both have Versa 2

I am having the same issue. Just finished a 50 min work out and while the tracker registered my steps, my active zones on hit 23 for the day. It's registering 60%of the work out as being below zone I don't sweat with normal activities 🤣

Here’s the short version — search through the mega-threads on the update itself for the long story: there’s an issue with the update affecting many aspects of our devices, HR while exercising being chief among them. Fitbit is not acknowledging this directly, nor is there any current plan for a patch/fix to correct the abundance of issues related to that firmware update. 

It’s up to us if we want to remain Fitbit customers.

Thanks MikePC for taking the time to respond. How disappointing that they are not actively providing a fix! I've only had my watch for a few weeks, feels like a waste of money now.
