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.
There aren't any restrictions hard-coded, but there's nothing preventing you from writing that logic in on your own.
Please let me know if you have any other questions.
Thanks,
Gary
What is Kinvey's policy towards malicious users using up my caps? Eg a user signs up for 10000 accounts and makes 1 API call on every one and thus accounting for 10000 Active Users or someone spams a bunch of push notifications, etc.
