Activating camera with 'Set Active'

@redbox Thanks, deactivating previous camera as you said did the trick! (screenshot attached)
Yes I can change and see through the cameras.

Is there a better / shorter way to achieve this?
Also I tried to replace ‘Set Active’ with ‘Set View Target With Blend’ node as you had mentioned, but it doesn’t let me attach from ‘GET’ node to ‘New View Target’ in ‘Set View Target With Blend’.
Thanks again.
