I’m getting this message from the Console
HTTP “Content-Type” of “video/mp4” is not supported. Load of media resource https://video.twimg.com/ext_tw_video/1230896921767706624/pu/vid/1280x720/wI7op_6fdVmi1MBx.mp4?tag=10 failed. [1234132226541064192](https://twitter.com/i/lists/1234132226541064192)
For example when I try to view the following tweet. Of course the link to YT is correctly shown, that’s not the problem I’m talking about though.
