## What Currently Happens?

Icons are **not visible** at bottom of screen. My workaround is to *guess* the icon location: I click the region where the icons *should* be to switch between GitPoint's four views (home/notifications/search/profile).

## What Do You Expect To Happen?

Expect four icons at bottom of screen to be visible, as shown here: https://apps.apple.com/app/gitpoint/id1251245162#?platform=ipad

## My Reproduction Steps

1. install on iPad
1. sign in to GitHub
1. no icons visible on bottom of screen!
