askvortsov Switching to a tag with a different template will only replace the content if you have not interacted at all with the composer. If you have added/deleted/etc text, the new template will not be applied
Unfortunately the template does not change if no edits have been made in the editor:
Flarum: 1.8.3
PHP: 8.2.22
MySQL: 8.0.39-cll-lve
