Good morning everyone, I'm new to the forum and looking for some help! I recently started using Twitter i'm still trying to figure it out as a I go. I've tweeted a few of my youtube videos... I've since changed the thumbnails of the videos drastically... Well when I go to my twitter it still shows my old thumbnails. It's been about 24 hours and the old thumbnail's are still showing. I was wondering will they update at some point or will they keep the old thumbnail design? -Thank you for your time!
