Broken in iOS 8.1. Works with 8.4 – Start Player Review

The latest version won't display on an iPhone 5s on iOS 8.1. Updating to iOS 8.4 resolves the issue. It does not "crash" as the app, with odd new/bad font size is displayed in the multi task view. However trying to access the app does not work and the app "crashes" back to the main iPhone screen.
