If(frmEdit.Unsaved, Notify("Unsaved changes", NotificationType.Warning), Back())Common mistakes & gotchas
- Back() pops Power Apps' navigation stack — it knows nothing about unsaved form state, so guard it yourself with something like frmEdit.Unsaved.
- If the navigation stack is empty (e.g. this is the first screen shown), Back() simply does nothing rather than erroring.
