Expected behavior

Local Data Mode must be usable WITHOUT having to call SDKManager.init() first, just like in previous MSDK releases. Otherwise, this would violate customers' network policies.

Agent comment from yating.liao in Zendesk ticket #87189:

Starting from version 5.5, there is a requirement for using a specific order. You will need to call the LDM-related interfaces after calling SDKManager.init.

If you have any further questions or need assistance, please feel free to let me know.
