Point 1: Actually, we are cahing this page so once you add video link for the instructor. Close the tab and then open appointments directory page in a new tab. Then check the video will work
Point 2: First we need to create a profile field, name it as “description”.
Then edit the field and add some text. Then Go to wp-admin > WPLMS > BuddyPress > Instructor Description Field and add this field name so the text will be fetched from here
This description will start appearing in the appointments directory
