This post is for our beta testers. Because we have sent you multiple versions of the GESTURES Camera app, they can cause conflict with each other when you try to share a photo on Facebook.
In order to resolve this issue, please remove all of the previous versions of GESTURES Camera app, and you must also remove access to the previous GESTURES Camera app on your Facebook as shown below:
Then restart GESTURES camera app and try sharing on Facebook. You will be asked to give permission, and you will be able to do so without problems. :)
