You are correct in your assumption. 8 gb emmc’s are already expanded. The process is only necessary for emmc’s of bigger sizes.
Regarding the mounting issue, this was in fact a bug caused by an Ubuntu update. We managed to fix it with a beta update. So you just need to click on the Beta-Update button under the Settings/Reboot menu in our web interface and your USB drives should be able to mount again.
