Respectfully, first and foremost, I was satisfied until the technical difficulties arose, and currently still difficulties at hand. I just purchased the master features less than maybe 45 minutes ago from writing this. Nothing about this feature is master when I can’t even get any sound when “casting” on my “Vizio” screen. You’d think we be in the game right, “Cast” feature plus Vizio, this app offering it, right? Well, that’s until you actually start casting, and you get no sound. It’s ironic, because if I Airplay it, it’s totally fine, sound, and picture. But for a customer to pay $2.99 for features, that you don’t even get, that’s not the full $2.99, maybe more like $1.99. I’m giving it three stars, because I know and believe these issues can be fixed. In addition to giving it three stars, to even contact you guys through your “app support” but can’t submit an email message through the support screen, but have to play math games to prove I’m not a bot, yeah, you definitely are getting three stars. Like I said, I believe these issues can be fixed. I look forward to it.
