I have the same problem.
I am playing everyday for 4 weeks (started to be active again after years of playing) and had no disconnections at all. It started approx. one week ago having a total of nearly 30 disconnections by now.
The behaviour: When i finished a stroke, my time still runs waiting for the handover to my opponent. After 5 seconds, i am thrown to the lobby and i have lost the game instantly.
Please dont tell its my firewall, router or my isp. My connection is very stable - for years.
I would be happy to give further details so you can reproduce that bug.
Thank you
