I am learning Digital Publishing Solution at the moment I am using the
30 days trial. I created my collection and the APP but I have a question
regarding how I can preview my collection. I tried to follow step by
step all the tutorials for the DPS APP Builder but when I tried to
create a new App, I fill in all the required information but it doesn t
allow me to proceed with the next page. Is it because at the moment I am
using the DPS trial? thanks Marzia
