As of April 12th, you must go to Progress SupportLink to create new support cases or to access existing cases. Please, bookmark the SupportLink URL and use the new portal to contact the support team.
Is there any plan to implement this still?
I believe this might be available now.
As you are a paying customer of Kinvey, you have access to Kinvey support portal. Can you open up a support ticket for this so that we can discuss this in detail?
