Hi Blake, I am facing the same issue. My Zenbook UX425EA got updated with Power Delivery FW upgrade and now my USB C-ports aren't working. The laptop is just 2 months old. Could you please tell me how to solve this problem?
I'm facing the exact same problem. After upgrading the PD firmware, the battery won't charge for 1%, it gets stuck at 40%. The customer service gave me instructions to follow, but the problem won't solve.
Which model do you have? UX425EA?
And even if you switch mode in MyASUS, the charging % does not change?
