Frank McShan, MacRumors:

Apple this past week had set purchase limits across several of its products. For example, the new ‌MacBook Air‌ and Mac mini were limited to five orders per customer, the new ‌iPad Pro‌ was limited to two 11-inch models per customer and two 12.9-inch models per customer, and iPhones were limited to two of each model per customer.

Why the limits? Could be a campaign to combat gray-market in response to supply chain shortages.

Why lift the limit? What changed? Not clear.
