Working in Funnel should always be fast and intuitive, which is why we're constantly looking for ways to improve performance and stability.
It's now quicker than ever to work with custom metrics and dimensions in Funnel. If you usually create and edit hundreds of mapping rules, you should have seen a significant speed increase.
We've also made improvements to the field editor, which makes working with rules containing chained expressions easier.
We hope that these updates provides a smoother Funnel experience. If you notice any performance issues in the future, please contact email@example.com and we'll be happy to help.
