The image you shared is the locked continue button. That should be unclickable until the video is complete and then the continue button will become enabled.
You said: when I play the video it still shows a 'Continue' Button and allows the user to click past the video.
If you don't see the locked continue button and it allows you to continue without completing the video, you can connect with our support team.
However, if you want to share a link to that lesson we can test it and see if it's working as intended before you connect with support.
