The problem is that the old InDesign CS6 started to work unstable and we removed it, but we cannot deliver by subscription - only versions 15 and 16 from the CC package are offered. What to do? There is an official subscription to all CC programs
CS6 is discontinued and unsupported. Adobe prefers their customers to use the latest versions. For this reason, only the last 2 major releases are available from your Creative Cloud desktop. Pre-2019 versions are no longer available.
