There are some old versions of SK Whatsapp like V20, V25, and V30. But I will recommend you to download its latest version as older versions may create issues in your android phones. You can join different groups, download status, and change your DP easily.
Here is a download link of the app. If the button is not working, comment in the below section to inform us about the issues. We’ll try to solve the issues as soon as possible. Also check pub whatsapp.
