I understand that you're facing an issue with the Books app on your iPad 7th generation running iOS 16.5, where it's not displaying the entire page of an ePub book and truncating the right-hand side of the page. However, you mentioned that the same book appears in its entirety on your iPad mini running iOS 9.3.5. Let's try a few troubleshooting steps to see if we can resolve this issue.
- First, let's ensure that you have the latest version of the Books app installed on your iPad 7th generation. To do this, open the App Store, tap on your profile picture in the top right corner, and scroll down to the "Available Updates" section. If an update for the Books app is available, tap on the "Update" button next to it.
- If updating the app doesn't resolve the issue, let's try resetting the app by force quitting it. To force quit the Books app, swipe up from the bottom of the screen (or double-click the home button if you have a home button on your iPad) to access the app switcher. Then, swipe left or right to locate the Books app preview, and swipe it up or off the screen to close it. Now, relaunch the Books app and check if the issue persists.
- If the problem continues, it could be helpful to reset all settings on your iPad, as this can often fix software-related glitches. To do this, go to the Settings app, tap on "General," then scroll down and tap on "Reset." Finally, select "Reset All Settings" and enter your passcode if prompted. Keep in mind that this action will reset all your personalized settings, but your data will remain intact.
If none of these steps solve the problem, it may be beneficial to contact Apple Support directly for further assistance. To do so, simply select the "Support" link on the lower left-hand side of this forum's web page.
