I have a Pi Zero with the cloudhub-pi0w-factory-sdcard image. It boots fine but every time I change any settings it reboots and restores to default. I'm using a 64gb microSD card that's been tried and tested with many other rasPi images on other pis. I emailed virtualhere and they said i needed to buy a license to fix this behaviour which i did and yet it forgets the license and restores factory settings on each reboot.
I know it's going to be obvious but what am I doing wrong?
