WHOOP 5.0 not tracking anything at night for the second night in a row

Hi All - I have had my WHOOP for a little over 30 days and now for the second night in a row it is not tracking my sleep or anything else from the moment I go to bed at night. It does show a gap in almost all metrics during my sleeping time at night.

I wear it on my wrist, snug tight, I tried to reboot it, unpair/pair again and still. Any one experienced this and what was the solution? Thanks in advance?

Yes, the same thing is happening to me. I have been a WHOOP user for over 200 days and the sleep detection started ~2 weeks ago. Prior to that it worked perfectly. WHOOP kindly replaced my sensor and the same thing is happening. Support thinks I am wearing my band incorrectly so I sent photos and also switched to the bicep band for one night. I am wearing it correctly, so something else is going on. Still unresolved.
