I tried to reproduce this today with no luck. I do have one question though – are users refreshing the browser after you change this? Because if not, we still have their old user preference data in the browser in ember, so the new preference will not be used yet.
For this to work as expected I did this:
- Checked on user A that editor was toggled to rich mode
- As admin, I changed the default to markdown mode and applied for all users
- As user A, reloaded the page and reopened the editor, and saw that it was in markdown mode
If I didn’t reload on step 3 there, I would still see rich mode.
