How do I apply a discount code?

The discount code can only be used during the test phase and is therefore only valid between the change from the test to the paid version.
To enter the discount code you have to go to the settings and in the settings you have to click on “General Information”.
The field for the discount code is located on the right side.

Please note that it is no longer possible to enter the discount code if you have already switched from the free version to the paid version.  Therefore please enter the discount code before you switch.
