Due to a bug the use of certain H5P elements is restricted. The H5P ‘Interactive Video’ element is particularly affected. So far, we have observed the following issues:

• LaTeX rendering in drag objects no longer works correctly: As a result, all questions that use LaTeX are currently unusable.
• Changed display of drag elements: The new layout alters the sizes, spacing and positions of the drag elements, meaning that many existing questions no longer function as intended.
• Existing drag-and-drop elements can no longer be edited: This affects image-based drag objects.
• Feedback is missing for certain question types: For ‘Single Choice Set’ questions in Interactive Video, the messages stored under Adaptivity (‘Reactions to user input’) are no longer displayed.

Unfortunately, there is no workaround. As soon as the bug has been fixed, we will let you know about the update here.

The following issues have been resolved so far:

• LaTeX display in drag objects
• Display of drag elements
• Editability of drag-and-drop elements

We are continuing to work on the issue of missing feedback for certain question types.

Currently, YouTube videos that have been embedded using H5P activity display ‘Error 153’. The error occurs on Apple devices only but is in relation to the used device and browser. The problem applies to the newest version as well as older ones.

YouTube videos embedded in H5P content currently have limited functionality on Apple devices using the common browsers Firefox, Chrome, and Safari. On macOS, they can be played in Chrome and Firefox, but in Safari, error 153 appears instead of the video. On iOS and iPadOS, error 153 appears in Safari, Firefox, and Chrome.
The cause is a bug in WebKit-based browsers combined with a change in the guidelines for the embedded YouTube player. Unfortunately, there is currently neither a fix for the bug nor a solution from Moodle or H5P. As a workaround, please use a browser other than Safari and a device other than an iPhone or iPad on macOS.
