Unable to swipe down on full screen iOS app

Appium version: 1.7.1 (Desktop)

I have an app that is in full screen mode. From what I have observed, full screen iOS apps require 2 swipes to bring down the notifications screen. Unfortunately, I am not able to get this to work.

The main reason I am trying to bring up the Notifications screen is so that I can use the search field to launch the Settings screen.

If anyone knows a better way to bring up the Settings screen, that would be great. Thank you!
