Quest 3 Charging Dock - Centre indicator light behaving oddly since V77

Since V77 dropped on my Quest 3, the centre indicator light, on the Meta Charging Dock, is staying at a solid amber, even though the Quest 3 light is showing green and the headset/elite strap with battery are 100% charged.

The headset still appears to be working, but the charging interface between the Quest 3 and the official charging dock, along with the official meta elite strap with battery is no longer behaving properly, as it was prior to the update?

I've tried shutting the headset down and then turning it on again, which initially sets the centre indicator light as green, but this turns back to the solid amber in a very short time.

Any suggestions as to how I might get my combo to charge correctly again?
