Is there any way to get the older version of the purchased plugin?

I have purchased Revolution Slider by Extended License. Recently, I had updated it’s version from 5.2.2 to 5.2.3 and it has a bug with bbPress, but it was not fixed yet(Visual Composer was fixed the issue by recent version) and I need to develop my theme continuously with it. So I want to rollback to version 5.2.2 but I have only version 5.1 which I had backed up. How can I get the specific old version of purchased plugin?

As there is no option to download previous versions on Envato, your best option would be to contact the author and ask them for the version you want.

Either contact the author or you could use a cloud backup to keep various versions
