Nap detection doesn’t work (for me)

I’ve been using my tactix 8 51mm AMOLED since March 31st. Since then I’ve been taken a couple of power naps but none of them has been registered as naps. My previous watch was a Fenix 8 51mm AMOLED and my power naps was registered with no issues.

My last power nap was today and it was 1h and 15min long. I had to register it manually.

Anyone else with this problem?
