MacBook Pro charger flashing on off
A couple weeks ago my computer started not always charging when I plug in the charger. It starts flashing charging, not charging, charging, not charging... I try all ports and flipping the USB C cable and still nothing. Eventually, sometime 20 min later, I find something that sticks and I am usually good until I back it up and go home. Then the same thing. I did all software updates and am now running Big Sur (I was on the old OS when this started). Not sure what to do and with the Apple store closed what my options are. Thanks for the help.
MacBook Pro 15″, macOS 10.12
