App Variable Trigger Event

Does anyone know why I can’t get an app variable change event to fire off?

For example, if I create a true/false app variable, then create an app variable change event and connect it to a pop up. Then on a different page connect the app variable to a button that when clicked changes the app variable to true…at this point the change event should fire on the first page and doesn’t.

Any help would be greatly appreciated.

Check the if formula and see if the right true/false value is triggered. You can also check the debugger to see if the app variable is being set correctly.
