So we are trying to get a start on migrating from Collector to Field Maps and are setting up our first map. We have an editable hosted feature layer, a template is set, the form is configured, and yet when we hit the '+' button in Field Maps it says 'No Visible Layers, Use the layer tool to toggle visibility'. However the layer is turned on and I can see, click on, and edit existing features. Any idea what I'm missing?
