Nik Software & MacOs Big Sur

Hello, indeed it works when we update Catalina directly with Big Sur, I tested it. But if you perform a clean installation with big on your disk, it becomes impossible to install the Nik Software collection again. The launcher always indicates a MacOs version problem. I can’t see anything on the forums or on the publisher’s site. Do you have any information please? an update ? Big sur will be available in final version in October … an update would be welcome!
Best regards

I got this from support :

"Greetings,

Our software will work with the public release of the software, it does not work on beta OSes, my apologies."
