Hi @MisssyCarol, welcome to the Community Forums.

Thanks for bringing this to our attention. To better assist you with this, can you please let me know when was the first time you experienced this issue and how many times since then? Which phone are you using to sync your Versa Lite? In the meantime I receive your answers, please restart your device, try wearing it on your non-dominant hand and let me know if the issue persists.

Looking forward to your reply.

Thank you for responding. I can’t wear my Fitbit on my other wrist because
of lymphedema. My Fitbit breaks my sleep in half or I’m missing one to two
hours.

@MisssyCarol Thanks for the details provided in your previous post, I understand where you're coming from. 

I'd recommend trying the following steps to make sure your heart rate is working:

• Switch the Heart Rate settings from On to Off and manually sync your watch. To switch the heart rate settings on your watch, from the main screen of your watch, swipe left until you see "Settings", next swipe up until you see "Heart Rate" and switch it to Off.
• Once it's done, manually sync your Versa Lite. To do so, open the Fitbit app, tap on the Account icon, tap on your Versa Lite's image and tap on "Sync Now" 
• Next, switch it from Off to On and manually sync your watch once again. 
• Once it's done, restart your watch once again. 
• Next, confirm that your tracker is snug on your wrist (the lights shouldn't be visible) We also recommend when you're not exercising, wear the tracker just above the wrist bone.

Also, for more detailed information, see What factors can affect my heart-rate reading on my Fitbit device? Keep in mind that active minutes are also calculated by your heart rate.

On the other hand, I recommend considering the following in order to get sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.
