How do I add more storage?

Hi,

As long as you only need to upgrade your iCloud+ storage, and not your device storage, you should be able to upgrade within Settings > Name > iCloud > Manage Storage > Change Storage Plan > select the preferred plan > confirm.

If you are experiencing issues with upgrading your iCloud Storage in your iCloud Settings, update your device to iPadOS 15.5.

You can't buy more storage for your iPad. See if anything here helps.
