my initial screen is “SearchScreen1” in Drawer Scene, when i use Actions.LoginScreen () for go to the login screen is work fine , but when i click back button back button work fine but not go to SearchScreen1, stay in Login screen, when I click again on back button in login screen this time is work and scrren change and navigate to SearchScreen1 i try back with Actions.pop() or navigation.goBack() , But it does not matter why can not back in first time ?

So use Actions.pop() no ??? Why keep using navigation.goBack() if it’s not working but it’s working as expected with Actions.pop() ?!

no , this not work . When I’m pressed the back button 2 times . this work Of course, with the code Actions.pop(). in first time not back to main screen . if i use navigation.goBack() , this never back
