UI Builder interface pages not displaying including 'layouts'

app no - A20959C8-58A0-45C4-BEEE-FF108415524A
I have another app which is displaying interfaces correctly.

I’ve found if I leave the webpage open then the user interface components appear but not in order or style they were created.

We had an issue with EU cluster (Performance Issues EU server).
Could you, pleas try again. And when you make a trial open the browser developer console in order to see if there any errors returned from the server.
