Tapatalk on Android

I downloaded Tapatalk for Android to access the forums as suggested in some posts, but when I tap “Add a site” and type “blender”, “blender artists”, “blenderartists.org”, “blender 3d” or “elysiun” I cannot find the site. I don’t even get CG related results. And I see no option to add a URL manually. How do I get it to work?

I’m having a similar problem with Tapatalk but for iOS, everything shows up fine except the subscriptions, I think perhaps the forum could be running an older version plugin for Tapatalk
