Trouble receiving OTP emails from Microsoft Partner Center

Hi Jill, it's not unusual for the partner support team to recommend opening the ticket with the M365 support team. Likewise, the M365 support team likes to recommend opening tickets with the partner support team too. For example when GDAP accecss was broken in the M365 admin portal, M365 support thought that GDAP being a "partner thing" was handled by the partner team. What they eventually realized is that the M365 admin portal is supported by the M365 team, not the partner team.

both teams choose not to take ownership of the issue until I was able to get a tech lead on the phone from both teams so they could work out who is responsible.

My issue is with the Partner portal. So, I will be very surprised if the M365 support team, who has historically only supported issues with the M365 admin portal, would take ownership of an issue in the Partner portal.
