In older iOS versions, you might receive an error message when displaying the page numbers in textbooks and exercise books. You will see first the following window: 
Some of the pages will still be displayed correctly, but soon you will receive an error message every time you open another page.
This error is present in operating systems earlier than iOS 17 and only in the Safari browser. To avoid this error, update your operating system or use mozaWeb in another browser (Chrome, Firefox, Edge, Opera...).
Official information about fixing the error in Safari 17 (failures due to exceeding the maximum canvas memory limit):
