@furykerry Apologies for the confusion earlier — thanks for your patience. I’ve updated the examples to use the correct SDK APIs, and this version should work reliably even in a clean, minimal setup, let me know if encounter any other issue.

[Daiwik-1901]

sorry for the failed cases I am open for suggestion to fix it.
