The buttons in the 'ALS Service Updated' app do not appear to respond to events.
SetupPage is currently the Start Page; it has a button with the text 'Button' which should navigate to a different page (CostComponent). But in Test mode, clicking on the button has no effect.
This is quite an old app, but has been updated for the latest Appery app builder as far as I know.
The app has been shared with Support.
