read e book digital editions on samsung s8 smartphone

hi, from a few days I use Adobe digital editions on PC (win 10) and now i want to use it on my smartphone Samsung S8.

I logged in with my account on my Samsung app, but I can't see the book I downloaded on it, I can see only the User Guide.... 

I use it in Italian.

How can I read the book on my phone?

Thanks
