I am in 30 days trial period of Dorico Pro 3.5 -- Can I switch to 4?

How should I do it if I want to switch to Version 4 when I am still in 30 days trial of V 3.5?

As far as I’m aware, you can request a trial of each product version separately – so you could either request a Dorico 4 trial now, or finish your 3.5 trial then request a 4 trial after.

Got it.
Thank you.
