Ryan,
Yeah, not sure what the Stack Overflow posts meant either. You *can* do your own redirects, but shouldn't need too. That's the point of the Mobile URL.
As for your issue though, I finally found a bug report on Facebook for users with the same issue. The problem is marked as "Fix Ready" which means it should go out over the next few days or so:
developers.facebook.com/bugs/280811108698311
Hopefully when that fix is pushed out, your problem will go away. If that doesn't look like your issue though, just let us know!
Thanks,
Alex
