Thank you for your post.
I replied to your similar post at:
In essence, FileMaker Go 13.0v5 and earlier did not take advantage of the full iPhone 6 and iPhone 6 Plus screen display. The display would expand under FileMaker Go 13.0v5 to fit the screen making it appear as an iPhone 5s. FileMaker Go 13.0v6 started to take advantage of the full iPhone 6 display. You will need to adjust your previous layouts to take advantage of the enlarged screen display.
You might consider adding a small invisible in browse mode object into the bottom right corner of the layout with right and bottom auto-size anchors set instead of the default "top - left" anchors. This will stretch your layout background out to the limits of the current display.
Yep, and moreover, to facilitate handling, i think this object can also be visible with a plain fill, but placed outside the layout boundaries.
Yep, but since that exploits an "undocumented feature", that just might get "fixed" in a future release of FileMaker, I prefer an object that is fully visible in layout mode such as a text object in bright red like:
With "Hide Object When" set to True.
Mmmh good idea indeed !
However, are you sure it is so different ? In the two cases, an invisible object alter the layout size...
One can say it is not "regular" and it maybe be broken on a future release...
I think the chances that a future "fix" of such undocumented and arguably "bug like" behavior (having the auto-size anchor options of an object not on the actual layout resizing the window) is many times more likely than the odds that a new version will keep a non visible object from re-sizing the window.
But I will also point out that the main advantage here is that my "layout stretcher" is very visible and clearly labeled for its intended function.
