Aspect ratio not supported

Does the developer of this app not realize that the photos most likely to be uploaded will be from an iPhone? Tried to upload several photos and get the aspect ratio not supported error. Ive tried both images made in Instagram ( square format) and default aspect ratio photo taken with iPhone. If the developer cant get this basic requirement right from the start then I have no interest in waiting around for them to "figure it out". App deleted.
Also check out the terms of service. While it states that you retain ownership of the photos uploaded another clause further down states otherwise. It states that any photos you upload they then retain the right license out. Could this just be a means of them building a library of stock photos for themselves?
