Hello there, @menendea, @jprobins83, and @anthony_ubelhor ...
The "RCE Auto-Save" Feature Option is something that can be enabled or disabled by your school's local Canvas administrator. You *may* be able to enable or disable it per course, but it also may be enabled or disabled without the ability to toggle it on/off one way or the other. That would be a decision that was made by your school's local Canvas admin. To check if you can enable or disable it in your own course(s), sign in to one of your courses in Canvas. Click on "Settings", and then go to the "Feature Options" tab. Do you see a row for "RCE Auto-Save"? If so, it may have an icon near it that indicates it is either enabled or disabled. You should be able to click on that icon to enable or disable it. If you do not have a row for the "RCE Auto-Save", then your school's local Canvas admin has probably enabled it for all courses at your school, and it cannot be enabled/disabled at the course level. You may want to have a conversation with your local admin to see if they would be willing to change the settings for that particular Feature Option slightly to allow you to toggle it on/off per course.
