I’m having the same issue with my Versa 3.
Our (my gf and I's) Inspire 2s just started having the issue as well. I'll spare you the support schpiel about putting it on your non-dominant hand and disconnecting/reconnecting to bluetooth because it's clearly a widespread issue not your device. But I did reboot mine earlier today and so hopefully it will properly track tonight's sleep.
I did disconnect and reconnect. It is working now. I have a older model a Charge 2. I do have to recharge the battery a lot, 3 or 4 times during the day. I was wanting to buy a newer model, but it seems like they are the same problems. I don't think buying a newer model with the same problems is worth it. I have always wore it on my non-dominant hand. I saw on QVC where I got this one the reviews are low for all the models there.
