Does zagg have a case and keyboard for iPad 12.9 2nd generation?

Being a Zagg product, your enquiry would be better directed at Zagg. However, having myself looked at the Zagg website, no products are listed for the second generation iPad Pro 12.9”.

Not any longer

Here is one, from Logitech, that will fit your 2017 2nd gen iPad Pro.

I found a NY Times article dated 20 August that refers to it.

The "ZAGG - Pro Keys Wireless Keyboard and Detachable Case - Compatible with The 2021 Apple iPad 12.9" Pro - Charcoal" is available through Amazon, but I couldn't find any reference to it on the Zagg website either - only for a 10.9 inch iPad.

The 2021 iPad Pro 12.9” is the fifth generation iPad Pro 12.9”.

The OP states that they are seeking a Zagg keyboard and case for a second generation iPad Pro 12.9” - which has entirely different physical dimensions.
