Just a quick question, I do not see a space at the Inventory for Up-Grade - the item you need for Evolving Porygon. Did I miss something?
I had one a few days ago, and it was visible in PF. But as far as I know there is no way to use it with PF.
YEs it's there IF you have an upgrade. If you want to use the items, simply click "use items" on the bottom right of the screen for evolving.
