ipad pro won’t charge

Check the charging port of the iPad with a strong flashlight and magnifying glass. Check for any lint, dust, or other debris. You can use a small, non-conductive instrument to try and clear the area, such as a wooden toothpick. Do not use a metal object, and be careful of all of the metal connectors there. You can gently blow out the section, and then see if the cables will make connection.
