I just want to mention that I have been seeing a few crashes in the Get it Straight application when users are trying to save their edited images to the Photos Library. I want to let everyone know that I have identified the problem and it has been fixed for the next update. The next update will come out when iOS 11.3 is publicly available which should be in about a week. Until then anyone who wants to save their edited masterpiece to the Photos Library can do that by using the Photo Editing extension right in the Photos app. Just hit the edit button then the circle with three dots inside it and you will see the Get it Straight icon where you can perform the same tasks and it will be saved to the Photos Library.
Thanks for your patience.
