On an odd occasion, there can be missing book covers on Pageticker on the parent app and the Teacher Dashboard.
We use the ISBN database for the book covers on Pageticker. If it is missing from the ISBN database then it will appear as missing on Pageticker.
We do have a process of manually checking these and adding any missing ones.
However, if you'd like to make us aware of any, please email us with the book title and author and a screenshot to support@pedalogic.com.
