Just wanted to check if I’m doing something wrong. I have wrist detection turned on my ultra, the band is not too tight but firm enough to not move about and makes contact with my arm near to the wrist bone.

But it still randomly locks. I thought it stayed unlocked whilst on the wrist

Anybody help as I’m thinking to remove Apple Pay if I can’t solve this?
 
Too loose, hardware issue, software issue.

I would wear the watch tighter for a while. If that doesn't resolve the issue then unpair the watch and set it up from new (don't restore). If that doesn't resolve the issue then it's likely a hardware issue.

EDIT: I'd consider cleaning the back of the watch. Maybe you do that regularly anyway, but some don't.
Also if you have tattoos, try the other wrist.

I had that also with one of my watches, in my case it was definitely some kind of software bug. I turned wrist detection off and back on again, from then on it worked perfectly

I have mine very loose and it never locks. So I highly doubt putting it on firmer would fix it. Perhaps tattoos could interfere with the detection? It works by shining a light and supposedly measuring how long it takes to reflect back, but that can't be the wholet story because it definitely knows whether it's close to skin or something else as it locks if it isn't skin.
