Plenty to squawk about. Painfully-thin documentation, stalls system-wide playing GoPro 4K claps on Apple TV 4K, crashes itself when screening 4 or 5 SD vids. PC app is primitive, crashes and shuts off Windows’ audio frequently — simply when being moused. Interface suffers from a tiny scrub bar with no jump-back/ahead buttons. Searching, skipping commercials a nightmare. Text only, no poster/album art. Weird green screen jammed up my AppleTV 4K this evening. Rebooted it, and my PC, every 30 minutes or so.
Much happier with FileExplorer Pro on my same system. Tap PC files, iPhone and iPad play/mirror perfectly, full documentation, a grown-up alternative with remote licenses for 6 family members included at a fraction of AirParrot’s price.
