My user's starting point is a Hamburger menu icon on my apps home screen:
The hamburger menu Icon gets you to this screen:
...and clicks on "issues by school" take you to another screen, but what appears to be a submenu to the user:
Currently, the hamburger menu icon is set to back() which does not achieve what the user would expect (that the menu closes and they are navigated to the last viewed gallery screen)
Instead, use my last screenshot as an example, the submenu list of the schools is displayed and the hamburger menu is clicked, you are taken back to my second screenshot where you would normally expect the menu to close completely.
So is it possible to formulate Back() to exclude all the "menu" screens and detect the last gallery screen viewed?
