Press and quickly release the volume down button.
Continue holding the top button until your iPad goes into recovery mode. If you're not sure, see which buttons you need to press to restart your iPad. Press and hold the top button until your iPad begins to restart. Press and quickly release the volume button farthest from the top button. If you don't have an older backup that was made using the current version of iOS or iPadOS, you might not be able to restore your device with your most recent backup.
Note that backups created while using beta software might not be compatible with older versions of iOS or iPadOS.
Then-if you have an archived backup-you can set up your device again from that backup. To remove the developer beta immediately, you need to erase and restore your device.
