I really use it on a daily basis, whether on my iPhone or on my Apple TV 4K. The Infuse + Synology DS218play couple works wonderfully. It reads all the files to me, whether it's 1080p or 4K HDR...a treat with my Sonos home cinema.
A small improvement to be made, the PIP function has been added to the Apple TV. Since it is available on iPhone and also on the Apple TV application, why not offer it as well?
But otherwise really perfect!!!
