This is not the place to talk to MS about it. this is a forum to help users. I'm annoyed, though installing the new may 2020 update through the insider system (just wait a few weeks if you don't know what that is) seems to have resolved it for me! I've had proper fast charging and no issues since installing it.
THAT BEING SAID IF YOU WANT TO TALK TO MS ABOUT THIS ISSUE OR ANOTHER ONE THERE IS A FEEDBACK HUB APP IN YOUR START MENU. that is where you can send info and issues directly to MS' developers. Give it a go!
