Yesterday I given PL-200 exam, and it been 24 hours still not received my certificate in portal and haven't received congratulations mail.

If you have taken the PL-200 exam and have not received your certificate or a congratulations email within 24 hours, it is recommended to wait a bit longer, as it can take up to 24 hours for results to appear in your Learn profile. If you still do not see your results after this period, you may want to check the following:

1. Confirm your login account: Ensure you are logging into the correct Learn profile. If you have multiple accounts, you might be checking the wrong one.
2. Check your spam/junk email folder: Sometimes, the congratulations email may end up in your spam or junk folder.
3. Contact Support: If the issue persists, consider reaching out to Microsoft Credentials Support for assistance with your missing certification.

These steps should help you resolve the issue with your certification results.
