I believe the OP is talking about the advertisements that appear in the lower/right side of the “desktop” : “when” you open the epic launcher for the first time each day, you have an option to close them if you want, an “x” appears in each add in the upper right corner of it, once closed it will “not” re-appear until the launcher is re-launched.
its not a big deal for me? I personally “like” the adds, helps me pick up free games when they come up, that otherwise I might not notice, since I go directly into the engine most days.
