Can't get the voucher but have an active license

I currently have Dorico 4 pro but when I activated my license for Dorico 5 upgrade but no voucher shows up for my upgrade.
What am I doing wrong?

Once you have completed the verification process for your update, the voucher should appear overnight (Germany time!) and appear the next morning. If it doesn’t appear, don’t worry: just let us know and we will be able to help you.
