iPad won't charge when powered on. Will trickle charge when off.

My iPad Pro 11” (2018) works fine except it no longer charges when it is powered on. When power is off it will trickle charge (sometimes). I’ve tried different USB-C cables and USB adapters. Visual inspection of USB-C port reveals no blockage or obvious damage.

Apple wants $500+ to repair. I’ve found this video on iFixIt that I’m considering iPad Pro 11" and 12.9" (2018/2020) USB-C Port

Hoping to talk to someone who has been through this process with my exact model iPad. The video shown in that link is clearly for a different model iPad (rounded edges instead of the squared off edges of my 2018 Pro).

Success? Failure? Caveats? What’s variations to demo should I expect between the iFixIt video and my iPad?

Thanks in advance!
