Cities not showing

Why is it some cities I’ve walked don’t show up under “Cities In Progress” even though recent activities list streets completed or progressed in that city?

You have to complete a street first. Are you sure they are completed ?

I was thinking that, but I have other cities listed under Cities In Progress in which I have completed 0 streets.

I was thinking the same, I’m sure this was changed some time back, that you have to complete at least one street for a city to show up in the city listing. But now when I check my isn list I see six cities with 0 completed streets at the end. So maybe @JamesChevalier changed this back for some reason?

Or possibly you had one street completed at some point, changes were then made to the street and now your progress on that street is below the completion threshold.
