The media sync can take a pretty long time at first, depending on your internet connection.
You can follow this tutorial to resolve the issue with missing media: Why is my deck missing images?
If this doesn’t resolve the issue, please keep in mind a few things regarding missing media:
- Anki’s built-in
Tools > Check Mediatool can sometimes show a “missing files” report even when no media is actually missing from your AnkiHub decks. - Broken image icons usually only indicate missing media if they appear in specific fields like Text, Extra, Sketchy, and Pixorize.
- For First Aid and B&B content, you will need a separate subscription to that resource. You can learn more about how this integration works here: McGraw Hill Integration FAQ
