Issue Description: Some Trainers who have not completed the Weekly Challenge before the challenge expires may be unable to close the Weekly Challenges reward screen to return to the Pokémon GO map. Tapping on the border of your screen that still contains the Pokémon GO map will allow you to exit out of the Weekly Challenges reward screen.

Issue Status: Resolved in the 0.391 release. Please update to the 0.391 release when it becomes available soon.
