I am trying to get my data setup for the Collector app. I have a feature service setup and I can see the map on the collector app. I am not sure why I have to be connected to the network in order to view the data. Then once inside the map is on the collector app I can add data but I do not get a sync option, but I can see the changes on the map from the service I created online. If someone could please help with this issue that would be greatly appreciated.
When you added the service, did you check the sync box in the feature access tab. If not you will have to change the layer settings. Also, you have to enable syncing in the web map when you created it.
One other thing to check, In the web map, you need to go to the Item Details and make sure that "Offline Mode" is Enabled.
I believe offline mode is supposed to be enabled by default. Make sure Sync is enabled on your feature layer and Offline Mode is enabled on your web map. When you are using Collector while connected to the network whether it is your Wi-Fi or Cellular it automatically syncs the data you collect when you hit Submit. In order to use the web map offline you have to tap the icon with the cloud and down-pointing arrow, set the basemap detail and extent, and you are good to go. When you go back to your map list that cloud with the down-pointing arrow will now have arrows pointing up and down, allowing you to sync the data you collected offline. Use the link mentioned above in conjunction with this one and you should be good to go.
