change signature no longer shows up as a refactor option

Hello!

Please create a default "Hello, World!" project (File | New Project > C++ Executable > Create). Does the “Change Signature” refactoring work in this project?

Well, creating a project from scratch did indeed give back the change signature option.   What's more is that when I then switched back to my own project the option was now there as well.   So I'm not sure what made it go away but it's back now which I guess is what matters most.

Thanks
