# Videos not syncing in the Meta Horizon app with Meta OS v77+

> LCK videos not syncing and showing properly in the Meta Horizon app with Meta OS v77+

Since the **Meta OS v77+** update, videos may not sync or display correctly in the **Meta Horizon** mobile app. While your videos should still appear in the app, they may be missing thumbnails.

You should still be able to **select**, **download**, or **play** them as expected.
