We want you and your learners to have choices. That's why we're giving authors more control over the lost connectivity alert in Storyline 360. With the May 2023 update, we've disabled the lost connectivity alert by default. This feature notifies learners and prevents them from continuing when their connection is unstable so they don't lose their progress.

Starting with the November 2022 update, learners saw a message stating they were offline and couldn't proceed with the course when either of the following occurred:

  • LMS statements failed to record 
  • Assets, such as images or videos, failed to load

When the LMS statement recorded or the asset loaded successfully, the offline notification disappeared, and the learner could continue taking the course. However, not every author found the feature helpful, especially as the default setting. The May 2023 update puts the decision to use it in your hands.

Enable Lost Connectivity Alert

Here's how to turn on the lost connectivity alert in your project:

  1. Go to the Home tab on the Storyline ribbon and click Player.
  2. When the Player Properties window appears, click Other on the ribbon.
  3. In the Connectivity Alert section of the window, tick the Prevent learners from progressing when offline checkbox and click OK.
  4. Save the project file to keep it enabled every time you open the project.

The notification color contrasts with the modern player theme color to aid visibility. For example, a dark theme displays a white notification with dark text and vice versa, as shown below.

The classic player always displays a white notification with dark text.

The lost connectivity alert is exclusive to Storyline 360, beginning with the November 2022 update. As of May 2023, we made it optional, giving you the choice. Projects published between the November 2022 and April 2023 update have this feature enabled by default. Existing published output will continue to work as expected. However, if you open that project in the May 2023 update or later, this feature will be disabled by default. Follow these steps to enable it.

Project files that use this feature won't open in Storyline 3 or earlier versions of Storyline 360. To restore compatibility, uncheck the box to "prevent learners from progressing when offline" in the player properties.
