My MVP arrived earlier and I've been trying to check the security code on the innokin website, with no luck. I tried it without spaces, with spaces, on my tablet, on my husband's laptop, my husband has tried entering it, etc. and it doesn't do anything. If I click the "ok" button, absolutely nothing happens. If I hit "enter" after typing in the number, it just empties the box. Am I doing something wrong, somehow? Has anyone else had this issue?
