Back button needed in landscape view for multiple windows

I’m running an Amazon Fire HD 10.
When in portrait mode showing multiple windows (2) there is not a “back button available” in the UI.

Do you perhaps mean there’s no direct back button from multi camera landscape view? This is a known issue. The workaround is to switch to single camera view, then emphasized text switch out of full screen which gets you back to portrait.

If it’s something else, please post screenshots of what you’re seeing.

Yes, my bad, landscape view is the problem.
Can you change the title please?
