On January 15, you shut down the servers that allow us to maintain this equipment (on-board therefore non-upgradeable).
No serious communication was made for this break in service. You leave your customers without efficient support. For a company that sells a support tool, this situation is incomprehensible.
Will you be making a real obsolescence plan for your old versions or will you continue to cut your customers brutally from your paid services? Your communication is not serious.
