One observation: the New UI so far is not yet for very large productions (2000+ elements) because of the very slow loading. As this gets developed further, this needs to be adressed.

after the install of a fresh minimal security instance of IRIS 2025.1, whenever I click on "Try the new UI" i am taken to a authentication page that shows Login Username and Password input forms with the Header "Interoperability". However, none of the known credentials on the system nor the UnknownUser seem to be accepted. Am I missing some setup step to define access to the new UI?
