Hi I’m Alvin. Your issue with the two 2C pieces sounds kind of familiar
with my experience when I tried to solve it. I learned the difficult way
that I had to solve the 2C pieces in a certain order, from in to out. I
can’t remember exactly what I did, but this is what I wrote in my
reflection piece back then:

"During this solve, my U+ and - cells are mostly invisible, and constant,
meaning that, for me at least, my U+ cell is always Pink and U- cell is
always orange. Because of this, I’ve learned the lesson, through the
difficult way, that I need to complete pieces in the U cells before the
others. When I was doing the 2c pieces, I had to destroy some of my solved
pieces so I can complete the U cell pieces, and then I had to go back to
solving the original pieces. Thankfully, this happened during the 2c
solving phase of my solve so I didn’t had to redo too much."

I’m not sure if this is that helpful. It’s been years since I’ve solved the
