I've noticed time and again lately that there are deleted videos in my notifications
Sometimes a video was only shown as deleted in the app. It worked sometimes on my laptop. Since this has happened to me every now and then, I'm not sure whether the video was actually deleted or that it is an error message or a bug from Youtube
For this reason I wanted to ask you to click on this link. What do you see there, does it say that the video has been removed?
"Video not available"
"This video has been removed by the uploader"
If you need the information about the video, you could have put it in a playlist you created yourself. Then you can go to recovermy.video and login with your YT account to find information about this video
