Just updated to the new app. Happy to see resolution switching! But playing back rips of my HDR Blu-rays buffers after a thirty seconds or so and then forces a transcode. I'm connected via wired gigabit and to the same switch as my AppleTV (also wired gigabit) which plays the same material back without any trouble in the Plex app and Infuse.
Also, no bit streaming audio yet is unfortunate. Still want to be able to playback HD audio tracks, including Atmos.
