MIB3 and playlists

Hi all,

Has anyone found a way to reliably use playlists on a MIB3 system? I'm still having the same problems that have been reported several times over the past year:

• When playing from a playlist, if I switch off & leave the car, the next time I start it has not only lost the place in the playlist, it has completely forgotten I was using one. Instead it starts playing at the alphabetically first MP3 file on the USB stick. My guess is that it's timing-related, the media player tries to play the files before the system has mounted the drive, but I've tried many different USB drives, branded and no-name, and seen no difference in behaviour.
• I have a folder full of playlists. These work fine for a while, but after a period (days, weeks, it's not consistent) the system no longer reports any playlists as being found. When I navigate to that folder on the USB drive I can see all the playlist files, but they are greyed-out and unplayable. The only solution I've found is to put the USB drive into a PC, create a new folder (e.g. Playlists2), copy all the .m3u files to it, and then delete the originals. It works OK again for a while, then everything vanishes again. My best guess here is that there's some caching involved, and for some reason the system loses the internal link between the cache & the files, which is why recreating them (as apparently new files) works.

I'm using a 128GB USB drive in the USB-A socket in the armrest box, but trying the USB-C socket by the ashtray didn't seem to change anything.

Thanks

Steve
