First, I should say to Allison Muise that the September 2016 update to Crowdsource Manager looks fantastic! - the ability to add a related record works seamlessly - very much appreciated.
The application now nearly covers every functionality my client is asking of it - however there's one last hangup. The Search Tool seems to be greyed-out and disabled.
Unless I'm making an obvious oversight, this behavior seems to be present both in the Sample application and in my client's version of Crowdsource Manager.
Here is the view from the Sample application,

And from my client's application:

As can be seen, both of the Search tools are greyed out and disabled.
Is there a configuration step I may have missed RE: the search tool?
Something to do with the layer not being searchable?
Thanks in advance for any advice.
