An update to this. You know how I google how to cancel a Nitro subscription, and the page I was supposed to go to wasn’t there for me in my account back then? Well, I got charged today! I got charged real money for this app which I still don’t know what it is or what it does. And I googled around some more on how on earth to cancel it, and it keeps showing that page that I’m supposed to click on the left side of the screen labeled Nitro which doesn’t exist.
Anyway, after messing with this stupid thing for half an hour, I finally found out how to submit a request, so I asked them to cancel my subscription and asked for a refund. Their FAQ says they refund within 5 days, so hopefully this won’t be an issue.
