Task state stuck at "New"

Unfortunately not. There are only a handful of cases where a client needs to perform some operation to let the task progress, but that's strictly in scenarios where the client explicitly tells the service to defer the request until a future date. I'm assuming you're making a simple reset request where you're not specifying some future event to wait for. In the majority of cases, tasks are expected to automatically start and be carried out by the service. Unfortunately this looks like a bug with the service and needs to be brought to the attention of the vendor.
