Apps won't default open

[ADAM ALI4]

On my old phone when on a webpage and o pressed an Amazon link the amazon app used to open as the default app. On the s9 plus it simply opens up a web page.

I have been to the app setting and tried to set this manually but with no suffice.

On my old phone when I installed a relevant lonk that could be opened with with the message open with "alway" or "just once".

Can anyone help?
