Videoscore not showing up + Ownership question

Hi there, I decided to try making some videoscores so I did a piano recording of a song I found on here that I liked: https://musescore.com/user/17558/scores/57997 as you can see it's a Zelda tune titled Graandma. So I clicked "make video score," put in my youtube URL, did the spacebar thing so the music lines up with the video, great. Here is the videoscore I made: https://musescore.com/node/1660451

The only issue is that there is no link to see the videoscore on the sheet music profile page. If you look at this page for example, https://musescore.com/the-wise-wolf/kindred you'll see its videoscore listed on the right just above the "Info" section. But why isn't the one I created on the page of the song I created it for? Does the owner of the sheet music page have to approve my videoscore to be shown on his/her page?

Another question is what is the point of a videoscore? I thought it was that we can SEE the piece being played by somebody. Many of the videoscores I've encountered are just people giving links to an mp3 of the piece on youtube accompanied by pictures or videos of a game or anime. Seems to me like a waste of time, if they want to see that kind of a video then the score's arranger should simply put the link in the comments.

And my last question is that at this point, it seems anyone can link any youtube video to musescore and turn it into a videoscore. To me that doesn't seem quite fair. As a teacher, I like the educational value it has but what if the person who posted their video on youtube doesn't want their video on this site? It could be just their preference or it could be that there's crucial information in the video description. As well, although the person who arranged the piece did the arranging, they did not compose nor perform the piece and using someone else's video can potentially give them undue credit. To solve this, I propose using a quick youtube account ownership verification that would work like this: when you put in a url to the videoscore, Musescore.com/.org looks at that page and finds the username, a PM is then sent to their youtube account with a 4 character alpha-numeric code (ex. 4H3P), collect the code from your youtube account, then you'll have to enter it back on your musescore videoscore page to verify.

Thanks for taking the time to read.
