Hi @Nandhini ,
appWindow is null if parent is in edge and child window is in IE mode or vice versa.
Child window could not get the parent window opener as well.
Parent Application has the logout and session handling functionality. It needs to close all the child apps on logout.
Yes, you're right. This is a known issue and hasn't been solved yet. I think we can do nothing but only wait for the fix from official. And actually they run in different browsers, so if you need to get the handle from them, I think this will be difficult.
And if you need to avoid this issue, I think you have to have all pages all running in same mode(IE mode or Edge).
In addition, you can send feedback on this issue, just press Shift + Alt + i
and edit your suggestion and send it.
Regards,
Xudong Peng
