Advance camera settings C1

[Derek]

When I try to set C1 or C2 to use "Advanced Camera Setiings" it works for the first try. Then nothing happens later if I press C1.
Can someone please advise if I'm missing something?
And now after further testing "Advanced Camera Settings" is not available to C1 or C2
Strange, something clearly I don't understand?
Need help

Using Go 4: Please try the C1 Advanced camera setting and advise what you think
Thanks....

It has never done anything when I've assigned it to a button.

Thanks for your response:
Yes nothing happened
But now in Go4 app I can't even find it too add?
And that's without an App update?
Very strange
