Fenvi FV T919 (Broadcom BCM94360) working except Apple Watch unlock (Catalina)

Hi. as the title suggests I have the above card and all is working well (including continuity and handoff) with my Wifi/BT card except unlock with Apple Watch. It looks for it and then resorts to unlock with password. I have had a couple of times where wifi was slow to start after screen turning off. My machine is set to never sleep. I have tried installing AirportBrcmFixup.kext with no change.

Anyone have any ideas or similar experience (and fix)?

Many thanks.
