If you open another Live tab computer or open the app while in Live on the website then that will happen (or if you do the reverse). I have only seen that occur in those instances.
About new v3 problems
Just trying v3. Only issue detected so far is "alignment" of things. For instance, in interactive chess diagrams (like the daily puzzle) all the pieces are flocked onto the a8 square. Works in v2 so no problem yet.

I refreshed the tab and it said another login detected. And i refreshed it becouse the clocks were not moving v2 rules only + in v3 is that you see the opening you are playing.

I have never seen that across a couple of different browsers. What browser and version are you using?


Sometimes the client will disconnect but doesn't indicate the status. Refeshing will often reconnect. If you are on v2, switching to v3 might help. If you are on v3, you should report the issue.

If it was a server issue, a lot more people would have problems.
That said, I have seen a number of posts with the iOS app so it may be possible the app has an issue, though it is also possible it is an issue with any of the hops the traffic takes from the client to the Live server.
As to opening a ticket you could always use a mobile browser.
Timers freeze sometimes + middle of the game says that another login has been detected when its not true fix please.
