Three devices that I rotate weekly: 10.5 iPad Pro on 17.3.1, 7th gen. on 15.7, 7th gen. on 14.8. All are jailbroken vastly expanding capabilities of iPad OS. I won’t update until iPad OS is revamped and can utilize the power afforded by the M chips. I don’t expect this anytime soon since iPad OS has been treated as an afterthought for many years occasionally getting iOS hand me downs. Will be happy if Apple proves me wrong.
