Board Thread:Support Requests - Designing Your Wikia/@comment-4356266-20150913150353/@comment-168424-20150915025855

What you're seeing is completely true and Wikia knows there are problems. You should take some screenshots and report the issues you're seeing to Special:Contact/bug. I haven't seen a problem with the mobile look not appearing. Make sure you have not clicked on something to force the desktop look. If you do this once, it may stick until you clear your cookies.

Here's what they've said they are doing to try to make it better:
 * They recently introduced Special:CuratedContent, so you can at least have some control over how stuff appears on your main page in mobile and a level or two beyond.
 * They are trying to unify the look between apps and the mobile skin.
 * They are adding more tools like Portable infoboxes and upcoming Flags (too hard to explain here).

I tried to get them to explain why they just don't give us simple tags to choose what renders on mobile vs. not and they were kind of vague. I suspect they are worried about breaking base MediaWiki rendering if they put something too general in or they don;t want to give admins that much control. They seem to be making a common UI for mobile a priority without admitting it.
