Left USB Ports not working
Hello, my macbook pro 2018 w/ Touchbar is not working properly. The USB ports on the left side don't function correctly. When I plug the charger into these ports the computer doesn't charge and shows something plugged in and then not plugged in. This repeats every few seconds. I took it into an official apple repair center and they told me nothing is wrong with it. I'm pretty upset about this since I had to go out of my way for an entire week to get this checked out as I'm traveling out of the US for the next several years and don't have regular access to an apple store. Why is my computer's ports not working and why is apple unable to do anything about it?
