I am a cis, male guy, who due to some hormonal issues looked androgynous and sounded like a girl when I was in my late teens and early 20s, and was addressed as "miss" quite often, and for the most part, people would just say "Sorry" when corrected, then address me as a guy.

Did you ever have someone insist that you're wrong? I looked quite feminine from childhood all the way to around 25-26 years old. I can think of several occasions where people insisted that I couldn't be a man.

The most positive one was when I was flying to the U.S., and ended up chatting with an elderly lady for a few hours while waiting for the check ins. She had a massive wagon with pots and pans and whatnot, and I had a tiny carry-on. Eventually we realised we'd forgotten to exchange names, so we introduced ourselves. She was like "but that's a boy's name", "well that explains why your luggage is so small!" and every so often she'd say "I can't believe you're a man" incredulously.

Worst time was when I was frequently swimming in my teens, and a Karen-type person walked up to me, insisting I put on a bikini because I'm too old to walk topless. It didn't register with me that she mistook me for a girl at first; I just thought this pervert old woman wanted me to dress like a girl.
