Description: This exemple shows when you group objects in two different ways and add a button to it.
Open the example file. Portal 1 you can scroll but not Portal 2 using FileMaker Go but it works for both portals on FileMaker Pro. The reason is how you group objects. This should behave the same way in FileMaker pro and FileMaker Go.
How to replicate: See the attached file
Workaround: Group the object in right order.
