Per ISS live-feed (https://www.nasa.gov/multimedia/nasatv/iss_ustream.html): Right now in a bit of tug-of-war between the Service Module (Zvezda) and the MLM (Nauka) which has lead to a bit of an attitude excursion. They're right now working to switch from the SM thrusters to the nadir Progress thrusters, station has been put into free drift while this happening. Things aren't helped by the unusual attitude of the station which is hindering station comms. Currently only have S-band voice/data, no Ku-band High Data Rate.
Another critical detail is that MLM commanding is about an hour away as even though the module is mechanically linked to the station, it still receives all its commands through the Russian ground stations. So no commands can be sent to the MLM through the Russian Segment of the ISS yet.
Latest: MLM has stopped its errant thruster firings and ISS is back in attitude control and all planned activities for the rest of day for the crew has been cancelled.
