Considering Elon fired as many people as he could, it's no surprise something is fundamentally broken and they haven't figured out how to fix it yet. Sucks it ate your money.
Many features broken now on X mobile app. Few weeks ago they remove swipe right to jump to the next video. Now they bring it back but you need swipe twice to jump to the next video, really annoying. Also timeline refresh randomly, the tweets I read gone before I finish read it.
