I couldn’t find setup files in Postman site for previous releases, there are some until version 8 but versions start with 9 do not exist in release notes/upgrade page ( https://learning.postman.com/docs/administration/upgrading/).
The issue is that I didn’t like the new interceptor and it caused some problems with existing API calls, such as, I was able to call an API with an intercepted cookie on version 9.7.1 but the intercepted cookie on 9.8 does not work for the same API now. I didn’t check in detail why it does not work, but I would like to downgrade postman for now to previous version.
