I created a navigation menu for the top of each screen using ClearCollect in the App section and a Gallery on each screen that references the collection. The menu gallery has a single button, and the collection has 8 entries. Everything works fine in the editor, and when I click Preview the app (F5). However, when I try to Play the app, the Gallery is not visible. There's a blank space at the top of the screen corresponding to where the navigation menu gallery should be. Sometimes on initial screen load there is a brief flash of vertical lines where the 8 buttons should be.
Any advice/help is appreciated!
Thanks,
Ron
