Copied the URL of the Netflix listings page from my laptop into Samsung browser, logged in as requested, and now each time I quit and re-enter the app, I'm straight in without having to log-in.
Couple of days ago signed up for the month's free trial of Netflix, and watched a movie. But since then, when I click on the Netflix app it still keeps inviting me to sign up for the free trial - the 'Sign In' panel is greyed-out. The only way in is via my browser and entering my e-mail and Password manually each time I want to view something. Don't have this problem with my synched laptop.
