Exfat/fat32 rekordbox playlist problems

I have an ssd that I have copied all my library over as a straight copy from Windows explorer. The ssd is default exfat. I cannot right click export playlists in rekordbox to this drive as it doesn’t recognise exfat. I have tried the engine route, but as you know there are issues with this showing 0 tracks in playlists. The ssd cannot be formatted in fat32, and Denon told everyone to use exfat anyway. I can do a few playlists onto memory stick which is fat32 and plug in prime 4 and it works. Why can I NOT do same for my whole playlist list onto SSD??? PLEASE HELP as ive had Prime 4 since day 1 but cannot use it how I want. Ive been on pioneer and rekordbox forever so when I saw the p4 and telling me I can convert easily from rekordbox, I went for it. But still NO JOY. Advice please
