You may find that a hyperlink doesn't work in this scenario:
- Initially, the hyperlink is covered or hidden by another object on the slide.
- Then, the object covering the hyperlink disappears via an exit animation to reveal the hyperlink.
This is a known issue. You can correct it by adding a motion path animation to the covering object to move it out of the way immediately after the exit animation completes. Learners won't see any difference, but it'll expose the hyperlink so it becomes active.
