I’ve been noticing that sometimes blocks aren’t showing any content and there doesn’t seem to be any apparent reason.
On this page, there is a video block under the header text, but the video isn’t showing! I have no clue why.
Sorry to hear of the problem you are having.
It is displaying fine for me as shown in the attached screenshot?
Is it happening for you on any particular browser?
Could you please test it on different browser?
