On request of the Ruzzle developers we asked you for information about the device you use to play Ruzzle, and the OS version that is installed on this device. In the end, however, it turned out to be a problem on the Ruzzle servers.
If new problems arise, you know where to find us!
First of all, the chat problem is supposed to be solved now. It was a server side problem and had nothing to do with what device you play on. Ruzzle team
