Mine disappeared too, I am so ticked off!
I’m having the same problem, I added two videos, one 3 days ago and one 4 days ago, and they arent showing on the feed to my website. It’s very frustrating, I don’t like the changes to YouTube..
Thank you, I wanted to be sure I wasnt missing a setting someplace. Now let’s see if my webhosting company and even understand the issue. I’m not hopeful give my past experience with them…
