First, try to pause and resume your upload by tapping 'check it out' in the upload element on the screen.
Then tap the button at the bottom. You can then tap it again to resume the upload. You may also be experiencing network issues getting in the way of a successful upload. If this does not fix the issue, please send us an email at firstname.lastname@example.org that includes the model of your phone, the version of software your phone is running on, and the version of the litterati app that you are currently using.
Please Note: do not log out of the app or uninstall it before your upload has completed. If you do, you will lose all the photos that were attempting to upload.
