[Stuart Wright]

Here is a video with a watermark logo bottom right, cards top right and annotations in the last 20 seconds.
None of them show up on Android.

Which is a significant problem as these additional elements are pretty important.
Is this issue related to the way Xenforo embeds videos or is it an issue with android?

If you play the video directly in the Android YouTube app, they don't show there either.

I think this is because YouTube hides these on mobile devices (interestingly if you set the browser to request desktop site, the annotations and logo do show). If you Google how to show annotations on mobile devices, there are various sources on how to do this. There are also resources on using cards which I believe Google intend to replace annotations.
