I’ve been hearing a lot about issues with trans people getting passports

Is this because they haven’t changed their gender yet or is it even if you’ve had all your documents updated they can still see that you were born a different gender so they can still fuck with your documents? I’ve had all my stuff updated since 2023 and I’m scared to get another passport just in case so I thought I’d ask first.

For more context: my ID says male and my birth certificate says male. Every document is consistent so I was just wondering if the problems are coming from people only having their gender updated on some documents and not others or if they’re denying passports to trans people who also have everything updated
