Most Apple Store locations DO NOT repair iPads, but ONLY offerr in/out of warranty device replacement.
If your expensive iPad Pro has paid, exetended AppleCare+, then a replacement iPad, of your exact model, in lieu of an actual repair will cost a small device replacement fee of 49 U.S.D..
If NO MORE AppleCare warranties, then an iPad replacement will cost you an expensive approximately 60% of that iPad's original OEM price from Apple.
Use the “Get Support” link, at the upper right hand corner of every Apple Support Community Webpage to attempt to schedule an appointment with your nearest Apple Store location, to get that iPad replaced.
Apple Store employees will be glad to help/assist you.
Sorry & Best of Luck to You!
