The tiles in the Additional Tiles section of your preview instance aren't working or displaying any content. For example, your Social Edge or Jive Extension Pack (JEP) tiles aren't loading, and the configuration menu for those tiles isn't appearing after you click on their gear icon.
This article describes a possible solution to this issue.
Please try the following steps:
- Uninstalling then reinstalling the browser you are using to access your preview instance. Please check with your IT team regarding this process.
- Clearing your browser cache.
