'trade_updates' not triggered for 'new' events

Hi, I am wondering why I do not get updates for ‘new’ events when running following python code for my paper account

async def on_order_event(conn, channel, trade):

If I submit a new order via the website, nothing happens. If I cancel the same order, I get notified of both ‘new’ and ‘canceled’ events:

trade Entity({ ‘event’: ‘new’,
‘order’: { ‘asset_class’: ‘us_equity’,

trade Entity({ ‘event’: ‘canceled’,
‘order’: { ‘asset_class’: ‘us_equity’,

Anyone got an idea why the first event is not triggering independently?
