Thanks Kanchana. I looked through the pdf you shared and have been able to replicate everything outlined there. With Khaled's help, I was able to enable sync on all the join views (it appears that the procedure has changed slightly).
On the web map, the offline settings now show up under the item settings and 'Use in Collector for ArcGIS' is also there. I am able to download the web map, but when I sync the map I'm getting sync errors. I think this is where your workflow is different than mine. I am making edits in Collector and based on your pdf, it looks like you're using S123 to make edits. Since there are edits made in Collector, I want to be able to sync these edits. The edits seem to sync fine, but I'm getting errors since Collector is trying to sync these join views which are not technically syncable.
My join view has the following, which leads me to believe that I should be able to set the sync direction to download.
"supportsSyncDirectionControl" : true,
This setting allows the client application to set the sync direction, but I can't find in Collector where I would be able to set the sync direction. I guess an option is just to live with the sync errors since the actual edits are syncing fine.
Any ideas on how to get rid of the errors?
