fpp in tpp games

Hi everyone! I’ve been playing PUBG Mobile and I’m trying to improve my gameplay. I was wondering—what’s the advantage of using first-person perspective (FPP) in a third-person perspective (TPP) game?

When is it actually better to switch to FPP instead of staying in TPP? For example, is it more useful in close-range fights, indoors, or in certain situations?

I’d really appreciate any tips or explanations on when and why to use each perspective effectively. Thanks in advance!
