I have settled a relatively new city with 11 citizens and it has had a Holy Site from early in its founding. It has my pantheon, but no followers of any religion shows when using the religion lens on the map. Does spreading with a religious unit have any effect on the city? When, under what conditions, will its citizens get religion?
Here is an image from the map. The city in question is at top-center: https://i.gyazo.com/767d76276e2643bb4606499f9a0d51a9.jpg
Note: A turn or two later, the citizens became members of religions. I am not sure what triggered this development. Perhaps my asking the question here!
