I installed the new update for Adobe Lightroom and now have the two versions, Lightroom Classic and Lightroom CC. However when I opened both programs seems to be the same.
When I open new Lightroom CC I'm see the old interface with all the modules, but I read that new Ligthroom CC has an look and feel similar to the mobile apps, centered on the picture itself, however I'm seeing the old classic Lightroom Interface
You are actually opening the old version of Adobe Lightroom 2015 CC which is the predecessor of Adobe Lightroom Classic. This does not always get uninstalled automatically when you install Classic. So no wonder you are seeing the same thing. Adobe Lightroom CC which you are referring to is a completely new program and you have to install it from the creative cloud app. It is completely different though and you should really think about what you're doing: https://www.lightroomqueen.com/lightroom-cc-vs-classic-features/
