No way to cancel “free trial” – Screen Mirroring・Cast・Mirror Review

I downloaded the app and it didn’t work smoothly. So I went to cancel the free trial and found an endless circle of links. Then I tried to contact the developer, and that led to a Facebook page. For real. I’m probably going to lose at least $30 before we get this resolved. Buyer beware.
