> This could be the first time I’ve ever downgraded an Apple OS.
> As we speak I’m downgrading the Snow Leopard partition on my trusty old Core Duo 2006 MacBook Pro back to Leopard (and while I’m at it, I’m finally getting around to upgrading the FreeBSD partition to 8.0!). I kept waiting for updates to fix the severe stability problems in the Finder, my FireWire 800 ExpressCard and my iMovie HD plugins, but I’ve decided to give up for now.
I know the OP was about iPadOS but same rules apply. Give the OS 27s a few minor version bumps and it'll stabilize. I'd argue OS 26's were worse at launch but they've gotten pretty stable in the last few updates (still ugly as sin on macOS though, Golden Gate is a huge improvement visually)
