The Bionic Reading add-on adds a script to your template, and it can still take effect even after uninstalling it. To remove the script manually without the add-on:
- Open the edit screen for any AnKing note.
- Click the Cards button to open the templates screen.
- Search for
_bionic-reading.jsin the front/back templates. You should find a line containing something like<script src="_bionic-reading.js"></script>. Delete it and save changes.
