The last official update was 2 days ago from Moussa:
Unfortunately regular updates aren’t very feasible. All I can tell you is ourselves and Microsoft are totally aware of the issue, and we’re in regular communication with them trying to find a solution. We have made progress with some platform bugs that affected some users, but we’re aware that many others are still having issues with 4K HEVC content. We’re working on it.
You’ll see me in a lot of these posts because I’ve been trying to make sure I get the information out as best I can.
