Chris, if you are the owner or an org administrator, you should be able to export the data from the feature service item page. By default, this is turned off for other users viewing the feature service item but can be enabled by the owner. We did find a small bug in our first beta release that does prevent you from opening the crowdsource layer in ArcMap or the ArcGIS Online map viewer. We have an update rolling out in the next week that should resolve this. Once the update rolls out, open the crowdsource story in the edit mode. When the app loads it will automatically update your story to the newer version as well as patch the bug in your feature service. Until then, you can still edit the Feature service with the REST API directly or with the JavaScript API. If you are planning to add lots of points I would recommend looking at some of the points you have added already through the builder so you can follow the same data model. The Crowdsource app requires a pretty specific data model and has extra validation built into the app to make sure your feature are valid. Also, the only attachments that the app reads are ones name "PrimaryPhoto.jpeg" and "PrimaryThumbnail.jpeg." All others will be ignored. The crowdsource app also optimizes these photos for the web so they load quickly. If you are adding point manually, I recommend resizing them before you upload. If some of the data is incorrect, there is a possibility the app will fail to load.
