A person who understands these things explains to us that, after being left out of several big multi-city campaigns, "Philadelphia will be a featured story. You'll have the option to add your Philly snaps to the Philly story. I think it may take a half day or a day for the City story to go live on the platform in the LIVE section."
Sadly, though, it won't be one of those face filters where you open your mouth and, like, a neverending hoagie comes out while your eyes go Kenzo/True Blood opioid black. Maybe next time!
