No licenses found since I updated to macOS Sonoma 14.2.1

I updated to macOS Sonoma - since then no licenses are found anymore. Do I need a new code for the activation manager? I wrote to the support yesterday but no answer. Thanks God I still have Dorico on my MacBookPro - (this I did not update, glad) -
I would be very glad, if the support would help me. Greetings

Installing Sonoma shouldn’t affect your licences.

What version of Dorico are you using? What happens when you launch it?
Where are you seeing “no licences”? What does the Steinberg Activation Manager app report?
When you sign in to the Steinberg website, what does it show?

Welcome to the forum, Christoph. I’m sorry you’re having problems with your licenses after upgrading your Mac to run Sonoma. In general there’s no problem with the latest version of macOS, so don’t fear: we’ll get you up and running again soon.

Can you please check you’re running the most recent version of Steinberg Activation Manager? (Running Steinberg Download Assistant will install the latest update if one is available.) What do you see in the main page of SAM?
