If you try to cancel online you have to do it through the desktop version of their site if you're on mobile (or just do it on a laptop or PC). I cancelled online last night and got a confirmation email right away.
They must have improved their customer service. I'm glad, because I was starting to panic after reading some of the complaints. If you're here freaking out like I was last night, just go to your settings in the desktop version and at the bottom is a cancel button. Click on that.
It's extremely easy - just answer a little survey to complete cancellation and tell them that, yes, you really want to cancel. I'll try to update later if I still get charged, but I don't think it's going to be an issue.
