Versa 4 stopped tracking my heart rate data accurately after the update

[GailI]

I recently did the update to my Versa 4. Since then, my heart rate no longer shows above 100 bpm even after being on a mini stepper for more than 30 minutes. Because of this, the zone minute are no longer registering.  Prior to the update, my HR on the mini stepper would be between 115 to 125 bpm.  I did do a factory reset thinking that would solve the problem, it hasn't.  Any suggestions as to what to do next.  This is very frustrating since I have linked the FitBit with my doctor's office.

Hi there, @GailI. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Versa 4 has stopped tracking your heart rate accurately. I understand how important this is to you and how you must be feeling, I will do my best to help you with this!

Please note that occasionally your device may have difficulty getting a strong signal, especially during exercises that cause your arm to move vigorously such as high-intensity interval training or boxing. Try to relax your wrist and stay still for up to 10 seconds. You might also notice a spike or dip in your reading as your device finds your heart rate. In both cases, normal tracking should resume shortly. 

Here are some tips to resolve heart-rate tracking issues: 

• Tighten the band so that it doesn’t slip on your wrist. For more information, see How do I track heart rate with my Fitbit device?
• Heart-rate tracking may not work with certain accessory bands, especially if they’re loose fitting. For best results, use the band that came with your device.
• Use the Exercise app to record GPS data for your workout. If you use MobileTrack in the Fitbit app, your heart rate might not appear on your device. For more information, see How do I use GPS on my Fitbit device?
• If you tried the other steps and don’t see your heart rate, restart your device. For more information, see How do I restart my Fitbit device?
