If changes you’ve made to a screen do not appear in Preview mode:

• Ensure you’ve saved your changes to the screen before previewing your course.
• Close the preview window and re-open one by pressing the preview button again or simply refresh the preview that is open. (Press the refresh button in the navigation bar or F5 on your keyboard for PCs, Command+R for Macs.)
• Clear your browser’s “cache” and then try opening the preview window again.
