@ranjeet-porter Can you provide more details on the issue? What are the steps to reproduce? What versions are you using? Can you provide sample app or code that can help us reproduce the issue to investigate and troubleshoot further?

[ranjeet-porter]

Hi @phantumcode I am trying to connect with broker and subscribing topic aggressively and from multiple points like internet change, workmanager, app launch, activity within app so facing this issue while using app.
