instagram profile photo not saving / working?

I've uploaded a basic photo to use as my profile photo it is 180x180, I click "edit profile" I select the image from my iPhone, it show's the image in the circle view, I click "done", the profile is refreshed but then there is no profile image! Do I have to do something else? I have tried logging in and out, and have also edited my profile information to make sure it is saving when clicking done. Any help would be great
