Ipad pro 12.9” first generation - audio devices?

Hi all,

I was very happy using my 1st gen 12.9” iPad Pro as a roon remote on the previous version - but now, with 1.8, my iPad Pro cannot recognise the audio devices, either on the actual iPad Pro or the devices connected to my core.

I can see the devices in my setup. The boxes for each device is grey (and I don’t really know what that grey means). Is it the correct colour for a working device? But it won’t let me select any of the devices, and it keeps failing.

To be frank, I am rather annoyed as I can’t use my iPad Pro but I was happily using it before the roon upgrade.

The language on my iPad is Australian English if that helps and I am using iOS 14.4 (18D52).

Any ideas?
