I am not sure about UCP wikis but on legacy wikis there should be an option to edit the mobile main page when you click the edit dropdown on the main page. Though, based on your earlier comment, I am guessing you already know that. As for not updating, it could be a cache issue. If you changed it and it still hasn't changed in a few days, then contact staff as originally suggested.
