I have newly purchased iPad Pro 11 inch 3rd generation

If your iPad shows signs of damage (or a broken screen as illustrated) when unwrapped, you should not attempt to use or activate the device. You should return the iPad to the retailer from which it was purchased - and seek replacement.

If you bought it via official Apple channels (Apple online Shop, Apple Store or Apple Authorized Reseller) you have 14 days (from the date of purchase) to return it and ask for a refund or a replacement.
