UPDATE: The authentication issue has been resolved. Subscription additions and changes are functioning as expected. If you experience any issues, please contact support.

ORIGINAL POST: We are currently experiencing issues with authenticating to Microsoft Partner Center from the V3 platform. Until Microsoft assists us with resolving them, any creation of new subscriptions or changes to existing subscriptions via the platform will fail. Any existing subscriptions will continue to operate normally and renew on their pre-existing schedules.
