Horace Dediu:

Instead of doubling its performance for the launch weekend the company only sold 25% more units. How can there be this discrepancy?

Is this a sign that demand is not growing at the rate we’ve become accustomed to?

Is it a sign that there are shortages of components or labor or other production problems?

No, probably none of the above.
