WordPress themes aren’t mobile friendly

I’ve been trying (though half heartedly up until now) to get my theme working on mobile for at least 6 months. It works great through a normal browser, but nothing is working properly on mobile. I’ve tried deactivating plugins and changing to a free theme, but no dice. At this point, I can’t even find the mobile selection in settings or appearance, though last I saw it, the mobile option was selected.

Any clue?
