If a page of the digital flipbook appears blank with just a grey X in the middle of the page. This indicates that the PDF for that page of the digital flipbook has not been created.
To resolve this:
1- open the flatplan and check that the page complete setting is switched on. If not then switch it on. Doing this starts the process of creating the PDF for the digital flipbook.
2- If the page complete setting is switched on > Take the setting off and put it back on again to regenerate the page.
Once you've done that, you may find that the flipbook page has still not updated. If that's the case the page will have been cached on your computer and you neeed to refresh it. Follow the steps in these notes to refesh the cache
