Summary
It is not necessary for Apple TV to do a logbox warning about async storage every time the app is reloaded.
This change just places the warning in a
dispatch_once()
so that it occurs only when the app is started.Test Plan
Tested using the app at https://github.com/douglowder/IgniteTVTest, which has the patch provided in this PR.
