Unable to complete Low-code App Builder Mission Exercise

I have completed all the training pre-requisites. However, upon clicking on Verify Mission Exercise button, nothing happens.

May I know how do I proceed to complete this final exercise?

Thank you.

@Hadig18 If it says that the Mission is not complete, it should list steps that you missed. If you do not see this, this may be a technical error. Please email [email protected] and they can look into your personal Pega instance and see what is causing the issue.
