Source sheet change

If I change the source (google) sheet (with same type of sheet) why I need to redesign whole app and filters etc? Is there any way so that even if change underlying sheet design or filters I’ve set will remain the same.

Because you are changing foundations of the structure for this screen… you have to build new one

What do you mean by “same type of sheet”?

If you replace it with exactly the same sheet/ structure it should work with all existing screens.
