I suggest to test this logged in as admin having two browser windows open side by side. On window 1 logged in as admin go to Site administration > Courses > Course default settings Make sure a new setting is present Show activity dates - showactivitydates Make sure default value is set to Yes On window 2 logged in as admin, go to Site home and click Add new course With the new course form open, expand Appearance Make sure a new setting is present Show activity dates Make sure default value is set to Yes Click on the help icon next to icon, make sure the text matches the prototype "The activity dates are displayed in the list of activities on the course page and in the activity" On window 1 , change the showactivitydates setting to No and save. On window 2 still with form open reload the page. Make sure default value for Show activity dates setting is now set to No On window 1 , change the showactivitydates setting back to Yes and save. On window 2 still with form open reload the page. Make sure default value for Show activity dates setting is now set to Yes Finish filling the form and create the course. Add a choice activity setting Allow responses from and Allow responses from to a date in the future. Make sure the activity dates are visible on the choice page. eg. Opens: 11 March 2021, 7:49 PM Closes: 16 March 2021, 7:49 PM Go back and edit the course again, this time changing the Show activity dates setting to No and save. Go back to the choice activity you have created. Make sure the activity dates are NOT visible on the choice page. Go back and edit the course again. On window 1 still on Default course settings change the default course setting showactivitydates to No and save. On window 2 reload the edit course settings page. Make sure default value for Show activity dates setting kept the value of the setting you have saved ( Yes )
