XF 1.5 Amazon embeds not working


I took a video of this using OBS (hastily cropped, apologies).


Here's our addon set:

I've tried disabling S9e (though the dev has updated it a few days ago with new Amazon codes) and it still behaves the same way. It's just blank, but if you edit the post, you can see the media code grabbed the relevant product ID, as such.


Alternatively, is there a way to just kill the Amazon media code, so at least the links will show up rather than blank embeds?
