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!)
