LR for IPad issues exporting to Smugmug

When it works, the app is fantastic. When it errors, holy heck it's frustrating.

When I develop my photos, 2/3 times I get "File could not be shared" error when I attempt to export it. The other 1/3 times, I get some sort of connection error with Smugmug. 

Process Used: Edit photo, pick export, to Smugmug. Once App says it has been successfully shared, I close all prompts and switch to Smugmug app as prompted.
