Profile support comes to Netflix for Android after update
Cake Boss, it will be because you started watching something similar.
If you've set up your Android device to automatically update apps, Netflix probably has already been updated to include the new profile support. If you haven't received the update, head over to the Google Play Store, open the menu (by tapping the "hamburger" on the top left of the screen) and click on My Apps. The update should be waiting for you right there.
In addition to the new profile support, the update brings enhanced search with support for people and related titles. And of course, there are the usual bug fixes.
