Cannot access SD cards larger than 8G

I made a small wav-music player with a STM32L452. Reads data from SD card via SD 1 bit mode, and plays it over the DAC. Homemade jukebox, fun little project.

My problem is: while all the small cards (up to 8 gig) I tested are o.k, larger cards do not work.

This seems so weird to me, since both 8gig and 16gig cards are FAT32, SDHC.

FATFS settings in cube mx are pretty standard, max_ss 4096, long file names enabled, max_lfn 255.

I am using cubeIDE 1.3.0
