Hello,
There has never been media in the BNB field so unprotecting that field will not download any images
You would have to reset local changes to get the HTML to appear in the first aid field
To do this:
Go to browse in your Anki → at the top click on the ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
No, we do not sync media in the first aid field due to copyright
We do not provide that as well, see more info here: Why don't I have all the media in the AnKing Step Deck?
