Some of my feeds are not loading images, see the example bellow. While the link to the page has images https://www.slate.fr/story/194442/vacances-stars-celebrites-ete-luxueuses-discretes-pandemie-covid-19
It is the same for youtube videos not loading I can see a space inside the text but not the video. It was working perfectly some times ago. Unfortunately I do not remember the date when this changed to help you pinpoint the problem.
Do not hesitate to tell me if you need more information to help you solve the issue.
Thank you for this great tool.
