> In a python client application, that is connected to a dispatch router, I have observed that the on_released callback was invoked twice for the same delivery tag.
> Here are the disposition frames I was able to capture for the respective delivery:
> {noformat}
> [0x562a0083ed80]:0 <- @disposition(21) [role=true, first=981, state=@released(38) []]
> [0x562a0083ed80]:0 <- @disposition(21) [role=true, first=981, last=982, settled=true, state=@released(38) []]{noformat}
> The delivery tag 981 came first without the settlement and next with the settled as true. And the on_released was called twice for the 981 delivery tag.
