Our API method
multi, used to batch requests, is now limited to a maximum of 50 users per call. This means that the included actions in the batch cannot affect more than 50 users.
This limit is intended to improve latency and better handle concurrent requests between API calls and the SDK, especially for user sessions.
How we handle concurrent requests
multi call is running, Leanplum will queue any concurrent requests (via the SDK or the API) for all users included in the
multi call, and then run the queued requests after
multi is completed.
