Leviton DW1KD-1BZ constantly unavailable as of a few weeks ago

Control of my Leviton WiFi switches stopped working yesterday

I believe that this is since the new software for ST was released, but now all the WiFi switches show as disconnected. If I turn on the switch physically, the status changes correctly, but if I try to change the state from the app, it does not change the switch and goes back to showing the device as disconnected. The My Leviton app still works correctly. Has anyone else seen this? Is it a bug in the new ST software? Is there a work around?
