I was using Filemaker Pro 12 until a few days ago when I updated to Pro 16. My file was made in Pro 12 and opens with no problems in Pro 16. What I can't get it to do is open in Filemaker Go on my Ipad. I resaved it but that did not work. I'm using Dropbox to upload it to the Ipad. I got it to work with a test file but not my old file made in Pro 12. Thanks for looking, hope you can help.
