Happy to help!
1. I was just wondering why I have to go to my email every time I go to sign in?
This is a security feature to combat account sharing!
2. is there a way to sign in to xbox or do you have an app for the smart tvs?
It all depends on what is on your smartTV. We don't have an Xbox App, but you could load it in the browser on your Xbox. If you have a Roku or Chromecast or AppleTV then that will work too. It all depends on your setup.
3. I got the code for the free food recipes and I don't know where to go to use it?
I'm afraid that section of SweatFlix has been retired in anticipation of a brand new system that is coming very soon! SweatFlix is now entirely workout focused. If you join the Insider Group then you will get lots of recipe support there.
4. I see other videos at the bottom that say buy but wondering if because I am a member do I still have to buy them?
Those are the same as the videos in SweatFlix but they are available to purchase so that you can download and keep them forever. SweatFlix is a streaming service which means that if you quit you lose all access. If you buy the packages at the bottom then you get to have them forever and watch them without an internet connection.
Hope that helps!
