I have added a 2nd portal to 2 different layouts, one designed for iPad, the other iPhone. The portal works as expected on my laptop (filemaker pro 14 advanced) on both layouts, but not on either iOS device. On the iOS devices I can see the portal border but no content. I have attached 4 screenshots, showing the difference.
There is no filter on the portal and nothing in the 'Hide Object When' box. The file is accessed from the same account name.
Any help greatly appreciated!
