I have a question relating to the same issue. I did the tutorial on creating a map with Damage Assessment. The map did show up on the Collector on my iPhone. However, when I created my own map with added layer of addresses and making the field editable, following the same steps as the tutorial, the map does not appear on my collector. I have tried refreshing, logged out and logged back in. The map is shared to the group like the tutorial one. Still only the tutorial map is shown in the collector and not the new map. Can you provide guidance? Thanks.
