If you have Android M or later, you may need to manually give Smart Receipts storage permissions: http://www.howtogeek.com/230683/how-to-manage-app-permissions-on-android-6.0/ And then try importing again. Certain apps (eg Dropbox) do not support the new Android permissions model fully yet, so it requires storage permissions to interact with. We're also working to ensure you get prompted to automatically provide storage permissions (rather than just an error) as part of a future update.
