I don't understand how a user would use filters in this app. The text below is from the panel in the configuration section. If the map had a layer set with a filter to ask for values but then the app was configured to ignore that filter, how would the user be able to set their own filter in the app?
Attribute filters that that use the option to 'Ask For Values' and the time slider will be exposed in Crowdsource Manager when they have been configured on layers in the map.
By default, the application will honor the initial values of these filters. If you use several of these filters, that may mean that no features are visible when your application loads. Optionally, uncheck the following parameter to choose to ignore the default filter and time slider values when the app loads.
