The new modern look for Power Apps is now available in Release Wave 2 for 2023. Users can toggle between the old and new look, but admins can remove this ability by creating a new solution in the Power Apps maker portal and adding an existing setting. The setting can be set to "No" and saved, and users will need to refresh their browser a few times for the setting to be removed. This can be useful for testing before enabling the new UI in production.
