From the latest iteration of C3 started supporting the "function" natively that means no need to add "function" plug-ins in your project and they ditched the old "function" plug-ins. The problem is with the old project which you created with the old function plug-ins you just can't import it to your newly created project. The error message is "function" object is missing. You have to recreate all the things which you have created with the old "function" plug-ins with the new native function.
So, my question is there any way to bring back the old Function Plug-Ins to my existing project? or is there any workaround for the same?
