Good to hear.
I've been away from it for a while, but have recently started using it again (with Carplay as well). It's working fine for the various hvec encoded video I've thrown at it so far, and Airplay to ATV is working too.
Is there any customization possible on the displayed titles for e.g. videos? For example, I use a dynamically generated field in MC for the title that incorporates some minimum amount of information into the title such as format (BD, UHD, 4K, etc...), which makes selecting from a list where multiple versions are available much easier.
