I can't get openlayers 6.5.0 to parse a WFS 2.0.0 response in GML 3.2, when the response contains multiple featuretypes. It' works as long the response contains only one featuretype.
I've put together a simple example with fake responses, as they come from our MapServer (7.2.2|7.6.2).
I think it's because MapServer has nested FeatureCollections in the response (same for GeoServer 2.17.0). If only one featuretype is returned, then the response has one level less and ol.format.WFS is able to read the features.
Am I missing something? Any advices?
