Apple Watch does not unlock iMac consistently.

Hi

I followed Apple’s setup including restarts. It works for a few times and then does not work. Our iMac has two accounts. Only one account has an AW.

It doesn't work consistently on my iMac or MBP either. It didn't with my S0 watch, S2 watch or now S4 watch. I am not sure why, but I have just accepted it won't work 100% of the time.
