Apple implements the USB-C/USB PD specs to a t and is unforgiving if you don't do either.

At work, our quick test for if a device implements USB PD correctly is to plug it into an Apple power supply (optionally with a PD protocol sniffer in line). If it doesn't work (either no/intermittent VBUS or the wrong VBUS), it's always been the case that the device is doing something wrong.

It can be annoying but strictly speaking their fault.
