I've been able to publish a collector service by making sure sharing is on then taking the map ID and addng it into the schema below. Sending the hyperlink email but when I open it to add a feature I don't see the button for adding an attahcment on my IOS device. the feature serivce is published correctly out of my 10.1 server and tested on a map that was created some time ago.
i've looked at the instructions on publishing and even if try to create a new map - now I don't get the publishing button as the instruction show which then forces me to add the map ID into the schema to open in Collector.
thanks
