Help from Peakd or 3Speak

10 days ago, a video(by #3Speak) of my son who died because of the vaccine was published in order for some to benefit from my experience. Then I could not bear to watch the video, so I deleted it, but I still see the cover of the video, even though I deleted all the content and tried to add different images, but to no avail... I hope someone can help me

This problem arises when you use #peakd
If there's no solution, I'm going to have to publish every day until this picture goes down, although I don't like this way because I prefer to write only a useful post.
