Change in stop times updates

Hi,

The stop times updates for buses seem to have changed. I am looking for the trip_id like so:

trip_id = entity.trip_update.trip.trip_id

but the trip object in the trip_update does not have a trip_id. This was working until yesterday. Is this change intended, or is it an issue? The “similar to” pane has just popped up saying that this has happened before in Nov 16.

Regards,
Ned
