Polygon SecondAgg Streaming Not Working

SecondAgg doesn’t seem to generate any events.

polygonStreamingClient.SecondAggReceived += AlpacaPolygonStreamAgg;

The other streaming functions work fine:

polygonStreamingClient.SubscribeMinuteAgg(Symbol); polygonStreamingClient.SubscribeQuote(Symbol);

Has anyone else seen this?

this is also my experience as of the last few days. The other data feeds work, but the seconds aggregates do not show up.
