Unfortunate.
If you purchased this iPad in 2020, even if you have any free, one-year limited manufauring warranty left on this expensive iPad, it is notoriously difficult to prove screen cracking is a manufacturing defect.
If Apple does NOT cover this screen crack as a manufacturing defect, be prepared to pay an expensive cost for another replacement iPad Pro.
