The app crashes after choosing to submit a shared story from the Global Shared Stories section. The story is, indeed, not shared, so I presume it’s crashing prior to anything being sent out. It seems to happen on all stories, not being specific to any of them.
This happens for me as well. Its quite frustrating - I am always coming across cool stories to share when browsing the Global Shared Stories, but then I get sad because the app crashes when I try to tell my friends
