I have a new HomePod mini 2 and am looking for a way to transfer a call from iPhone to HomePod without having to manually press the transfer message that gets displayed on the phone. I was able to do this with the HomePod mini original generation.
I am running v27.2 on both the HomePod mini 2 and iPhone 12 mini.
Currently, I get a message 'Tap to transfer...' which works, but is clumsy and I would prefer to have the handoff occur automatically as it did with the prior generation HomePod
