This issue is still reproducible on the Firefox Reality version 7 RC3 (7b66fb1) build, tested on Oculus Go (Android 7.1.2), Oculus Quest (Android 7.1.1), HTC Vive Focus Plus (Android 7.1.2) and HTC Vive Focus (Android 7.1.2).

Some videos still don't load and instead display a black screen. Clicking on the black screen will result in an error message being displayed inside its bounds. Attached are a logcat file of the issue and a screenshot of the error message displayed.

I can't reproduce this issue. Could it be a intermittent Youtube server error? I've seen that error on Desktop too (rarely)
