I've just created a new Instagram account for showing my designs and I've downloaded the Instagram app on my Android (Galaxy S4) phone. I'm able to share my .psd files to Instagram directly from the Creative Cloud app, as well as generic image files (gif, etc). However, when I try to share .ai files to Instagram I get an error message, "Unfortunately, Instagram has stopped." Has anyone seen or fixed this problem on any kind of phone? Is this a known issue?
