I’m having some strange problems with my 1st gen 11 iPad Pro. I bought an aukey 65w charging brick and the iPad does not charge (usb c to usb c); not even a message saying it’s not supported. The iPad Pro also does not charge with the apple 18w charger. However, it does charge with usb a to usb c cable and it does charge using the MacBook 61w charger, usb c to usb c. What could the issue be here?
