Moving apps to SD card, Sony Xperia E5

[10smears]

Hi guys,

So I've recently upgraded to a Samsung (I know, I'll sit on the naughty step!) 64GB microSD card as my 16GB SanDisk one was too small. I thought, now I have all this extra space, I should move some of my apps over to save space. But it comes up with a message "not enough storage" when I try to move, and I know that both my phone and SD card have plenty of storage.

Any help is appreciated.
