Hello, I have a problem with starting the VPN Client service. During the configuration, I need to enter a username which, in the case of my VPN service provider (Getflix), has the format "VPN-123456". Unfortunately, the text field does not accept the "-" character in the username. The service provider cannot change the username. This issue was not present in the previous firmware version, but after updating to the latest version last week, there is no option to revert back. What should I do? Is there any way to work around this problem?
