Why is there a shortage of Strattera?

I'm curious, why exactly is there a shortage of Strattera? Is it due to supply chain disruptions caused by the pandemic? Or is there a manufacturing issue at the company that produces Strattera? Are there any regulatory changes that have impacted the availability of this medication? It's concerning to see patients struggling to access a medication that is crucial for managing their ADHD symptoms. I'd like to know more about the root cause of this shortage and what can be done to alleviate it.
