Can't change the thumbnail on one of my videos?

[RattlidgeGaming]

I recently uploaded a video and whilst it was in the process of publishing it gave me the standard 3 thumbnails, I didn't want to use any of these so i tried to insert my own and it wouldn't change it. In fact it won't let me even pick another default thumbnail. Any ideas why?

Try clearing your browser cache and reuploading the thumbnail.

Youtube doesn't always update right away so just be patient. If in a day or so it's still the same, clear the browser cache and reupload the thumbnail again.

It's probably your browser's cache, to clear it press CTRL + F5 on your browser. It should do the trick!

I guess Beastby is right!
This kind of thing happened to me before, I think I cleared the cache! it worked

I've had that exact same problem, and clearing my browser's cache definitely worked, so do that!
