everything in my new model 3 (2018.24.1) works perfectly.....except I can play music from a usb flash drive. Bluetooth audio is fine, fm is fine. started with usb 3.1 drive with about 6 gb of mp3's formatted fat32. tried both front ports, rebooted, tried older usb 3.0 drive also fat32 with only 3 files at 3 different bit rates, also tried in both front ports. whatever i do - the flash drive is read in, all the songs/artists/albums are listed, correct album art is displayed by each song, but ANY song I try to play leads to a failure to load error. not one song has played. help?
