P.S. I am not using Incognito Mode (just dark mode/black layout) if that helps at all with determining the problem. The first screenshot has the copy/paste username input on the left while the typed username input is on the right. The other screenshot displays the error when I try to login with my typed username.
Hey. . . this is an edit. On closer examination, I realized the apostrophe was probably slightly different on the typed UN versus the copied/pasted UN, hehe. Is there anyway Support could change my username easily so that I don't have paste my username all the time? No idea how to change the keyboard stuff on my computer so that it uses a certain character over another. Might create a new account but I don't necessarily want to create another email. It's no biggie really.
