Hello @Zoran23,
You don't say which of the two versions of the App you use. There's an iOS and an Android version.
On the Android version tap on "Profile" at the bottom right of the screen. Then scroll down to find "Switch to hosting" and tap on that. It will then be in hosting mode and you'll see "Inbox", "Calendar", "Listings" and "Stats" at the bottom of the screen.
I don't have an Apple device so can't give detailled instructions for the iOS app but I'm sure there is a similar process for it.
Steve.
