How do I remove a Happy Santa app?

You need to open the Manage section of the community, select Apps, find the app you need, then click EditRemove application.

Please note that all settings will be saved when you remove the app, so if you want to add it again, the same parameters will already be in place.

Take a look at the button below the appĺs window. For apps created by third-party developers, the community link is located there. Apps created by HS have a button in the same place that can be used to ask Support a new question. If you see this button, this article will help you. If you see a community link, please contact the developers of that exact app.
