As per our /about page, we have 20,000 members.
I will clarify that the steps are as follows:
- Visit /admin/site_settings/category/all_results?filter=default_composition_mode
- Set default_composition_mode to Markdown mode. Even when it’s already in Markdown mode, you can open the dropdown and select the Markdown option.
- Get the warning for XX number of users. Accept it.
- Wait ten minutes, and then reload the page.
- Set default_composition_mode to Markdown mode (same as step 2).
- Again, get the warning for the same number of users.
As you mentioned, I also don’t know how long it takes (over 10 minutes?) to update the historical user preferences. Also, I don’t think all those users would have updated their preferences back in just that time. I could be missing something here.
