Hi, for a few days now, Youtube embedded videos do not show as image preview neither in the composer nor on my home page, which uses the Topics lists plugin.

Victory ! That solution worked: After playing around for a bit, I disabled the “Block onebox on redirect” setting, which fixed the issue for youtu.be links, although I need to rebuilt HTML on old posts.

My issue seems very similar to that one: Youtube issues after update
