iPad 10 download issue

Hello Christy-fl,

Thanks for posting in the Apple Support Communities.

It sounds like you're unable to download a book after purchasing it on your iPad, right?

If we have that correct, let's first confirm that you have the latest iPadOS version installed to see if that could be related to what's occurring. If an update is available, be sure to complete a backup prior to installing the update. Should you need assistance with either of these steps, check out the following resource: Update iPadOS - Apple Support

If you have the latest iPadOS version installed, the following resource includes helpful steps when you're unable to complete a download with Apple services. We'll include information below to check your Wi-Fi connection as that will help to isolate if your network is preventing the download, and you can find additional steps to try here: If you can't connect to the App Store, iTunes Store, or other Apple services - Apple Support

Make sure that your device is connected to the internet

Use any web browser to connect to any website. If nothing loads, use another device on the same network to see if it can connect to any website. If no other devices can access the internet, turn off your Wi-Fi router, then turn it on again to reset it. If you still can’t connect to your Wi-Fi network, contact your internet provider for more help. If only your first device can’t connect to the internet, get help with Wi-Fi on your iPhone or iPad, Apple Watch, Apple TV, or Mac.

If you use cellular service to connect to the internet on your iPhone or iPad, make sure that you have cellular data turned on for the app that you're using. To do this, open the Settings app, tap Cellular, then turn on Cellular Data.

We hope that's able to help. If not, provide more details on which steps you've tried and any additional information that you think may be helpful. We'll gain a better understanding of what could be occurring to provide you with the best next steps to take.

Have a a great day!
