Acrobat Pro 2020 Licenses Expiring

@Michael30714328jij0  In the context of Adobe's software, "end of support" often means that the software will no longer receive updates, which can eventually lead to compatibility issues with newer operating systems or security vulnerabilities. 

Whether or not the software will "no longer function" is a more complex issue. Generally, perpetual licenses, like those for Acrobat Pro 2020, allow you to continue using the software. However, the lack of updates can create problems over time. You can likely continue using Acrobat Pro 2020 after the end-of-support date. However, be aware of the potential risks associated with using outdated software — Adobe will no longer provide updates, security patches, or technical support for the software. 

If security is an issue, Adobe encourages users to transition to their subscription-based Acrobat offerings (Acrobat Pro DC or similar). This ensures you always have the latest features and security updates.
