TV Cast Chromecast for Android

How do I go about canceling my subscription

Going to charge me for using my chromecast that I paid for, IN A PIGS EYE.

Tried 27 different ways, deleted everything stared over - you name it - app doesn’t wokr

I recently stayed at a hotel that forced you to use this app as the only means to use the tv. Needless to say we ended up not using the TV since this app is nothing but a mediocre cash grab 1) advertised as “free” but not only are simple features like pausing paid, but it sticks a giant banner onto the screen rendering your movie unwatchable. Don’t advertise as “free” if that version isn’t actually useable 2) The app doesn’t even support all websites, for example Netflix isn’t supported 3) I understand the age old “we need money to keep running” excuse but your app is unusable as free, and mediocre at best even when working. I won’t be bullied into paying for features that should be built in like pausing and rewinding. Come up with an actual idea worth paying for and improve your business practices, then maybe people will consider buying your app

Terrible, it doesn’t work anymore after replace a new router. It’s used to be free and now cost?
