Adobe Digital Editions and Big Sur

Other communities have access to a developer(!) version of the new operating system to be prepared in time... However, some companies like Fujitsu and Adobe show, that they always fail with such option and still await the final release and also after the final release need months to adopt their software. However, the next MacOS already following up Big Sur has already been announced (and is available as beta again), but Adobe still fails to get all its applications compatible? Adobe Digital Editions is still missing in the lists, but maybe also because they do not focus as such on a solution, where they are in the position of a monopoly.

You may also check roaringapps for compatiblity, however, for Big Sur there is no information.
