    Yes  the setting is On.  I opened a ticket with MS and they directed me to this alternative, however my app is more complex that what StartScreen can accommodate.    My understanding was that App.OnStart should still work as usual, but not for me.  If I use the Navigate function anywhere in my App.Onstart then I cannot set any global variables, using the function Set(myVar, "whatever").

    What do you mean "no longer sets variables"?  Do you have the "Enable Navigate function in App.OnStart" feature set to "On"?

    My app no longer sets variables in App.OnStart if the Navigate function is used, and the logic in my app isn't supported in StartScreen.  The setting,  "Enable App.OnStart property", is On.
