It is now difficult for us to maintain several versions of Arena and to offer them on the different stores (Windows & Android). In addition, the validation times do not allow us to be as agile as we would like.
This is why we have decided to discontinue support for the downloadable versions of Windows and Android. Since these versions are wrapped web applications, it is easier for us to maintain their online counterpart. Current versions will cease to work at the end of the current cycle on November 27, 2020.
Thus, users of the Windows version are encouraged to uninstall the application in favor of the browser version, and users of the Android version are encouraged to use the generic mobile version.
