Thanks for reaching out. Just to confirm, does this happen across devices/browsers? Also, do you see the same on the video manager? Send a few screenshots our way and we'll take a look. Keep us posted.

I've tried it on my phone, tablet and laptop and it just won't update! It looks as though it has, but then you refresh and the screen is blank again
