After creating a activity in the Content Builder, you have to send it to the platform.

In order to do so you have to click on the 'Push to TinQwise learning platform' button in the Content Builder.

You can choose to push a single activity or a complete folder.

When pushing a complete folder you see which activities will be pushed to the platform.

Select the correct platform and click on push.

The activity(ies) will show up directly in TinQwise Control under the tab Content > Activities
