Hello Roy_G_Biv2,
It sounds like your iPad Pro will not turn on with normal turning on procedures after you've shut it off and you will have to force restart it, right?
Which iPadOS version are you using on the device? Have you tried to update the iPad? If not, you can look at the steps to do that here:
Update your iPhone or iPad - Apple Support
"Update your iPhone or iPad wirelessly
- Back up your device using iCloud or your computer.
- Plug your device into power and connect to the internet with Wi-Fi.
- Go to Settings > General, then tap Software Update.
- If you see more than one software update option available, choose the one that you want to install.
- Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do."
If you continue to encounter the same behavior, contact Apple Support.
Regards.
