Text font in Settings → Appearance - Attempted several different fonts, no change
Minimal Theme Settings → Editor Font - Attempted several fonts, and no font when using other methods, no change
CSS Snippet - Attempted several font changing css methods found here on the forums, no change
Attempted all above changes while also toggling on/off and uninstalling individual community plugins.
What I’m trying to do
I am attempting to change the font in the Editor View but none of the above mentioned methods are working. The Settings → Appearance → Font works for all fonts EXCEPT Editor View. This problem does not exist in a separate Vault with the same plugins installed.
A month or two ago, I had a similar thing come up. The solution was make sure all plugins were up to date (I never did figure out which one was causing the problem) and restart Obsidian. (I may have also restarted the whole computer in the process, I don’t recall.) I’m guessing you’ve already tried this, but throwing it out there just in case.
UPDATE: I have fixed my issue, though the reasoning behind the fix is still a bit perplexing. In my previous attempts at getting the font changed, I had attempted switching off the Minimal theme entirely and reverting to the base Obsidian theme, with no success. However, today I switched to an entirely different theme, really just looking at themes, not even worrying with the font issue, and the font changed! Switching back to Minimal theme does NOT break it again. So something to try, switch themes around a bit!
