Based on what (admittedly little) I know about at-scale production of consumer electronics, it isn't exactly easy to just "produce a ton more" when they realize the demand. It is also difficult to tell what the cap on demand is. If they think they satisfied maybe 70% of the total demand for that product with the N-Number of units they produced, they may consider that "good enough" and not worth launching another production run.
