Trade updates not consistent

After submitting a trade it is critical that I get an update on what happened so I can plan the next step accordingly. Even though I have subscribed to trade update, it seems I only receive some trade updates some of the time. In fact I don’t receive most of them, no matter if they are executed through the website or through my program.

I’ve noticed that this is also extremely common based on the unanswered posts here. Is this something the developers are looking into?
