I am facing the same problem and lost cash so many times.I had contacted support .They told to check my firewall and clear the cookies and other few things.My net was working well without any problem.My other poker application are working well without any problem but the problem is with bet365 only.
If for some reason if the net get disconnected for a second then other poker application does not exist and wait or try to reconnect but bet365 application get exist fully and we have to again login ,till that time if we have raise chips in any game then we might have loose that chips .Similarly I have loose so many times.But they are unable to accept the problem is from there side and say they are working on this but who is going to pay cash that we have loose due to such issue.If in sit n Go turnament if it disconnect one time it is ok but it get disconnected deveral times which is not good.
From my point of view they have to make changes in there poker platform as it should not fully exist.
Thanks,
Suryan.
