I have a solution that has stopped working properly on devices running IOS 10.3.1 (and maybe back to the original IOS upgrade) On devices running IOS 10 and FM Go 15.0.4, graphics embedded in buttons and container fields, are being displayed as a solid black square or rectangle. Devices running IOS 9 with FM Go 15.0,4 are displaying the graphics and buttons correctly, as they have for a year or so. We only found the problem on iPads that had came back from the field where they never had wireless access, and hence never had an IOS upgrade, and subsequently did an update. iPads still out in the field running IOS 9 are working fine.
Computers running MacOS X and Windows are all fine.
Is this something other people have found, or should I try to submit a report directly with FileMaker?
