Right now we only have a reliable jailbreak (checkm8) for up to iOS 18 (and that's only thanks to one iPad model). Some app developers are pretty aggressive about dropping support for older iOS versions.

This affects iPhone XR, XS, 11, SE 2nd gen, and a smattering of iPads. Many of these devices got the iOS 27 beta and will likely see future iOS versions for at least another year or two.

Edit: here's the affected iPads:

* iPad Pro 11" (gen 1-2)

* iPad Pro 12.9" (gen 3-4)

* iPad mini (gen 5)

* iPad Air (gen 3)

* iPad (gen 8-9)
