Apps management

Hi!

is my first iPhone. I have some doubts. Because I don’t know if the device has a fail or works so.

1) when they send me a link from “not private” Facebook account, in android, i used to click on the link, and android automatically opened the link AT FACEBOOK APP. In iPhone no. When I click on the link, iPhone ignores that I have installed the app, and sends me to safari and ask me to open session in Facebook, to see what they sent me.

that’s Normal? iPhone works so clumsily? Or is something wrong with my device ?

I’m starting to regret of mi decision of buy an iPhone 😰
