roCodeRegistrationScreen

You ought to be able to recreate the screen manually using scenegraph labels, buttons, and tasks (timer, rourltransfer, registrysection) to talk to your server.  That's why it's been deprecated.  You'll want to be using those basic components in your code for various screens needed by your app anyway, so it's a good idea to get comfortable with them.  It took me about 4 hours to figure out how to display and update text on the screen, but then I'm not the brightest person... 🙂  If you have access to rokubilling on your account you can use their billing sample app to link, eliminating the need for the rocoderegistration rendevous linking code.  https://blog.roku.com/developer/2016/07/13/channelstore-node-billing-guide/
