Ipad air 4 stage manager?

Feature availability is usually limited by system hardware - CPU and available RAM being critical to advanced functionality such as Stage Manager.

The new Stage Manager feature was originally being developed for iPad models with an M1 SoC/CPU, but was later extended to include iPad models with A12X CPUs. As such, this feature is available for these models of iPad:

• iPad Air (5th generation)
• iPad Pro 11-inch (all generations)
• iPad Pro 12.9-inch (3rd generation and later)

You can use Stage Manager on these iPad models:

• iPad Pro 12.9-inch (3rd generation and later)
• iPad Pro 11-inch (1st generation and later)
• iPad Air (5th generation)

Your iPad Air 4 does not support Stage Manager.

No one promised stage manager compatibility for the iPad Air 4th gen. The 5th gen iPad Air was released 7 months ago, 3 months before Stage Manager was announced. At that time the iPad Air 4th gen was discontinued for sale by Apple.

Unfortunately it is a hardware limitation. There is a difference between the A12X processor and the other A series processors. In fact, it was the basis for the M1. This is the reason that some older devices may be able to run it while newer devices are not able to do so.

I have a brand new air 4, was promised compatibility, and…Nope.
