Hi, I find that even when I have set “default\_composition\_mode” to Markdown mode, users on my forum are getting served the Rich text editor on starting a new topic. The forum version is “Discourse v3.5.0.beta9-dev — [Commits · discourse/discourse · GitHub](https://github.com/discourse/discourse/commits/08e9f9c00b) — Ember v5.12.0”.

Each time I apply the change, I am prompted “Would you like to apply this change historically? This will change preferences for 15 existing users.” and I click Yes. Even then, users being served the rich editor. Is this a known bug?

**Edit - note** : I have this issue with users who never used the toggle option to swap their editor mode between rich/markdown. They just logged in today after I had already set the default composition mode on the weekend right after the upgrade. I had also hidden the toggle option via theme CSS.
