Webhooks limits: ambiguous
Limits: By default, each client ID can have at most 10,000 subscriptions. Also, you can subscribe to the same topic at most 3 times.
Seems to be ambiguous to a lot of developers, they seem to think the that "3 times" means they can renew it 3 times then they are SOOL
Limits: Each client ID can have at most 10,000 subscriptions. Where you can have 3 active subscriptions to a topic at the same time. Where an active subscription is defined as a topic/callback pair.
