Encountering an irritating number of devices that are charged/powered via a USB-C port but that don’t work with a USB-C pd charger (only with a USB-C to USB-A cable).
Bonus irritation: a device with a USB-C port that works with a PD charger only if the cable is plugged in one orientation, but will work in either orientation if connected to a USB-A charger. (A Phillips rechargeable pocket work light).
@mattblaze I happen to deal with a lot of standards professionals in my day job, and I can tell you that what you amateurs might call "incomprehensible and unpredictable ways" they would instead refer to as "flexibility."
