What an amazing achievement. From the outcome, it sounds like all the hardwork has paid off. Congratulations :)

How have the users perceived the new version so far? Are there positive feedback? Any new complaints due to the parity issues? Or in general, how is your team measuring success of the UI? From the post, it sounds like the users have a way to provide feedback and your team has a way to engage with them, which is wonderful. So I'm curious to learn.
