Nighthawk M1 MyMedia support

Hello.

I have tried to open MyMedia with several memory cards formatted as both NTFS and FAT32 of these brands:

THN-M302R0640EA - Toshiba Exceria 64 GB microSDXC

THN-M203K2560EA - Toshiba M203 256 GB microSDXC

SDCAC/16GB - Kingston Action Camera 16GB microSDHC

Only the last one worked. So my question is, does the device even support the SDXC-protocol and cards over 32GB in size?

Error message:

To use MyMedia, please ensure a compatible micro SD drive or USB is inserted to your router. Only NTFS, HFS+, HFS, FAT32 and FAT16 formatted media is supported.
