Check out our TV app and tell us what needs to fixed!
Hey all, X TV coder guy here 👋. Earlier this week we launched highlights on user TV profile pages, so you can pick what videos show first on your TV Profile. I also want to follow up on some of your most common complaints: - Fixed an issue on LG TV that forced users to log in again every time they reopened the app. - Major performance refactor of the video player. The controls should lag a lot less. - Added support for styling captions in the video player settings menu. - Fixed an issue where videos on the homepage would jitter from reloading after returning from another page. Download it now on your Samsung TV, LG TV, Amazon Fire TV, or Google TV before they send me back to the mail room. And I'm sure you'll all feel more than welcome to send your numerous ideas / complaints in a reply. 😂  (Seriously though, we appreciate it!)

We’re starting to launch the block function update
Soon we’ll be launching a change to how the block function works. If your posts are set to public, accounts you have blocked will be able to view them, but they will not be able to engage (like, reply, repost, etc.).

We're rolling out a new block option only for DMs. It prevents an account from sending you messages while enabling you to continue to interact with the account in other ways. This is another step towards our evolution of messaging on X - stay tuned!
