Legacy Creative Suite will not be updated to work on Catalina. If you have a legacy CS product, your road ended at Mojave or earlier.
Creative Cloud users should be aware of the known compatibility issues on Catalina.
Personally, I would defer upgrading to Catalina for at least a month while the dust settles.
Is this still an issue? That is Deamweaver and other 2020 apps not yet being compatible with Catalina?
No. This discussion began last summer when Catalina was still in beta testing.
Dreamweaver 2019 and 2020 are Catalina compatible with these known issues.
