Ipad Pro stuck on the apple logo

Have you tried a Factory Restore of your iPad?

Restore your iPhone, iPad or iPod to factory settings – Apple Support

If the Factory Restore was unsuccessful, the remaining self-help option is a DFU Restore:

If still unsuccessful, you’ll need to seek assistance directly from Apple Support; the link to Contact Support is at top-right of this page. Alternatively, as visit to the Genius Bar at your local Apple Store will provide opportunity for Apple’s helpful staff to take a look.

If iPad isn’t responding, do one of the following:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On an iPad with Face ID: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.

If your iPad still doesn’t turn on, or if it gets stuck during start up, see the Apple Support article If your iPhone, iPad, or iPod touch won’t turn on or is frozen.

You’re very welcome. I’m delighted to learn that the problem is now resolved.
