LinkedIn app not allowing in app pop ups

Hi all,

I am trying to use a company's careers page to apply for a job, but when I need to sign in to my account it looks as though the LinkedIn app for IOS is not allowing the pop up to appear. I can open the required page via opening the page in the browser, but not within the app itself.

It works fine with Android, so am pretty sure it is an Apple App issue.

Do I need to speak to LinkedIn and not Apple?

Any help greatly appreciated.

Graham.
