I see there’s a discount for new users to purchase X2Pro5 until the end of today 29th February.
But I cannot see a discount for existing users to upgrade, is there one please?
Once you purchased X2Pro5, any updates / new versions are automatically free on the App Store. The purpose of the discount in general is to encourage existing users of X2Pro to move to X2Pro5, there is no mechanism in the AppStore to provide a subsidised path from the legacy product to the new one, so what we decided to do was to run discounts periodically on X2Pro5.
