Hello LIU, CHIA-YEN,
after completing the necessary modules, it may take up to 48 hours for the badge to appear in your profile under the “Other” tab.
If the badge is still not visible after this period of time, some users recommend checking the “Modules, Courses & More” section under the “Achievements” tab in your profile, as the badge may be displayed there.
If the badge is still missing, it would be advisable to contact Microsoft Training Support directly for further assistance.
If this is helpful, please accept the answer. Thank you.
