Hopefully someone catches wind of this and fixes the problem. No one you can really refer this issue too.

I was able to register and today is the day of the training but I've been in the lobby waiting for almost 20 minutes

Same here. waiting in lobby to be let in and event says it starts at 11am EDT. And it's 35min past start time.

Guess the event was cancelled? No notification email or anything.

Answer 1

The behavior described matches other event/registration issues where the problem is on the event platform side rather than the local device or network. Since trying multiple devices and networks did not help, further local troubleshooting is unlikely to fix it.

Use one of these supported paths:

Re‑attempt registration later or from a different browser or private/incognito session, in case the event system is temporarily unavailable.
If the issue persists, contact Microsoft event/certification support so they can check the specific event ID and registration status:
- Use Microsoft Certification Support as a general entry point for event/exam registration issues: https://www.aka.ms/credentialssupport
If a reminder or follow‑up email for the same event arrives, check it carefully; some users report that a different action link in the reminder email (for example, a separate manage/cancel/confirm tab) works correctly when the original link does not.

If support confirms a platform issue and the event time passes, the usual resolution is to register for the next available delivery of the same event.
