Starz log in and apps

Is there a way to log in on the x1 for my password for starz? They had a special for the year that I have already purchased and just wanted to use it but the only option is to subscribe. I saw a post from 3 years ago that didn’t get a follow up so I’m curious if this has been updated or not? 

also is there a way to rearrange the the apps on the Home Screen? It seems like there should have been an update to the interface to accommodate there issues?
