It’s probably part of the database migration but I encounter issues where places added to foursquare in the last half year or show don’t show up in the app list
One example is this location: Michette - Michette - Bakery in East Somerville
This is the same as this one: Delay on new FourSquare locations being available in Arc?
I’ve done some testing, and am seeing the same problem, so I’m going to have words with Foursquare. I’ll post follow ups in the other thread, to keep it all together.
