Access problem with mobile interface

Hello. I set up group access rules that gives users the ability to only create and modify editorial assets within a certain section. Upon testing this, I discovered that the access restrictions do not apply if the user switches to the mobile interface. That means the user could modify as well delete any article no matter what section. Is there a way to make the group access rules apply to the mobile interface? I love the mobile interface -- very clean and easy to use -- and was going to recommend it to my writers. But I'm not so sure I want to give them across the board access.
