In any case → click on "continue on this device" solves the problem

What happens if I click "continue on this device"? you will be able to take advantage of your account on this device and all your other devices will be disconnected. You will always be able to reconnect to it, up to the limit of $this.View.AuthResponse.DeviceLimit devices.

How can I see the connected devices? go to your customer area and click on "manage equipment". If you go there after clicking "continue on this device", there should be only one.
