Activity
Initial work towards this JIRA went in this PR: https://github.com/caskdata/cdap/pull/6549/
The third part is still pending. We need to come up with a build process for SDK to be uploaded to cask.co/downloads that alone will show the user registration form. Assigning this to as he is currently working on it.
We still need to implement the final settings process to show the registration form on specific build + integrate the form with marketo (or other appropriate API).
This PR fixes splash screen to be shown only for website SDK builds. https://github.com/caskdata/cdap/pull/7157
