I am unable to link to a YouTube video in my Experience settings.
I have tried the “share” version that YouTube gives you, and the “direct” version straight from the Url of the YouTube page. Both fail to be submitted on the Experience settings form of the website.
Here’s what I see on the website. I have tried on the “new” Experience settings page and the “old” one, both were the same:
They might mean that you need a “Youtube channel” rather than “Youtube videos” so maybe they are trying to prevent NSFW content or videos or just trying to prevent “Off-site” Promotion
I ended up creating a PlayList on YouTube, and added the target video to that Playlist. The form allows me to use the PlayList’s url instead of the direct link. I am not sure why, but I’m unblocked by using the PlayList instead.
