Usage Guidelines
- Recommended: ~25 tokens per subscription. You may have multiple subscriptions on a connection.
- There is no “hard limit” on how many subscriptions you can have open on a connection, but we generally recommend ~20-30.
- Your internet connection, and geolocation (proximity to US-West), may affect connection health and speeds, especially with many subscriptions.
- See our Subscriptions concept for more information.
