To create a YouTube subscribe button on Dubb, simply add a call-to-action with a URL and enter a URL like this in the web address field: https://www.youtube.com/dubbapp?sub_confirmation=1

Make sure to replace “dubbapp” with your channel username or ID.

Make sure to add an internal title, button text  (e.g. “Subscribe on YouTube”) and specify if it should be a default CTA in your dashboard.
