Micro-sd card usage topic

I purchased a 64gb Samsung evo microsd card for my tab s 10.5 16gb.
I am currently on the bliss ROM lollipop and cannot move any apps to the microsd card , I just get the error 'cannot move app'.
I am rooted and have tried all the apps like app2sd, etc. But none work for me, is it even possible?

Currently the format is ext4 unsure if this is the problem, when I received the card I got the same error although unsure if the card was ntss or fat32.

Any help would be appreciated .

Thanks

James
