How to downgrade Photoshop CC 2020 to any other version?

Direct Download Links https://prodesigntools.com/tag/ddl MAY help
-you MUST do what it says in Note: Very Important Instructions
-https://prodesigntools.com/adobe-cc-2015-direct-download-links.html#download-instructions
-the prodesign links go directly to Adobe's file server, so this process
--will only work until Adobe completely removes the old version(s) from the server
.
When you do have a download, be sure to copy it to AT LEAST one external device
-since Adobe does sometimes remove old versions from the server
-a usb flash drive or hard drive, or write to a DVD

i just downgrade my CC to 2019. I contacted adobe via chat on adobe websites.

First, you will chat with a bot, and you just need to tell that you want to download another version of CC.

And then, you will be given a choice, which i choosed: "get help to download, install or upgrade".
Lastly, you will be directed to someone, and he/she will ask which version you need, and he/she will give you a direct download link that will only available for 24 hours.

Hope that helps.

Moved to Get-Started

Adobe changed its support policy and the only supported versions are the two most recent, which is v21 and v20.

These should both be available to download from the CC desktop application.
