Thanks @WesBurke!
Good to know about the edit URL, and that maybe YouTube Shorts for whatever reason work differently than YouTube proper. It seems to work as a link instead of a video.
One thing I still had trouble doing was editing the project text. I was able to hit edit and get to the screen to change my text, but when I attempted to submit it gave a 400. I just added my edit to the comment instead, but that maybe something worth looking at.
I’m currently on Firefox in Ubuntu 18.04.
Thanks again!
Edit: And thanks @adrian2301 too!
