Twitter has announced they will be killing off their apps on several platforms, such as Xbox, Roku, and Android TV.
Their pulling the plug on the aforementioned media boxes might have to do with their poor reception (Twitter for Xbox has an average rating of one and a half out of five stars), and their need to change the platform to comply with the European Union’s requirements for the upcoming General Data Protection Regulation that will come in to effect this week.

However, Twitter is still available on both Amazon Fire TV and Apple TV.
