Here's the solution from SAi:
There is a known issue with the Iphone 7 photos specifically (it has to do with the ICC profile that gets imbedded into those photos). The issue is resolved in the latest service pack (SP3) for the program, if you update to the newest version it will be fixed. You can force the update by logging into your account on
www.saicloud.com with your email and password, then downloading the software. When installing, choose the option to overwrite, then near the end make sure you do not clear preferences (if you do, you will lose your print setups and personal settings).
