Your web browser is probably storing an old version of the page. Manually refresh the page and the latest information should appear. Use Ctrl+F5 on a PC or Cmd+R on Apple.
If you are viewing after saving to your device's home screen, and not a web browser preview, then you will need to swipe the app closed from the recent apps view of your device and then reopen fresh from the home screen icon.
If your preview brings up a blank page then please check the System Requirements here.
If this doesn’t resolve the issue then please send us a message through the support tab with some details of the updates that you have made but can’t see and we’ll get right back to you.
