I have the same problem. New phone and the well running existing network (M4 3x) is not recognized. It´s the android version. Can you help me? Thnaks and BR Andreas

@TP-Link How did you solve your issue? I have a new mobile phone anf the same problem. I can login but no chance to add the M4 network that is running. I don´t want to make a complete setup again. So...
