You can see when other team members are editing a quiz. If someone is online and making changes, their avatar appears next to the block being edited. Hover over the avatar to see their name.
When a team member is editing a block, it turns gray, and others cannot edit it. You can make changes to the quiz once the team member finishes editing and moves the cursor away from the area. If someone is adding, editing, or deleting images or videos, the area is not blocked.
