I'm creating a task in a subsite using call web service action, Task gets created and assigned to user, however does not trigger email notification that it is supposed to be sent upon task creation. (This is for a Task list that has email notifications enabled in advanced settings) Tried creating a Nintex WF but it does not trigger either.

Also when the task is created and assigned to user, it does not get recognized by the list as it does not show under My tasks.
