If you can’t stand iPadOS 15.4’s performance on your iPad, note that you can’t downgrade to older iPadOS software.

Apple has stopped signing on iPadOS 15.3.1 which means you can’t move your iPad back to the previous version of iPadOS in an effort to improve its performance. Unfortunately, you can’t move your iPad’s software back to anything older than iPadOS 15.3.1 either.

This means those of you jumping up from iPadOS 15.3.1 and below should proceed with caution. Once you make the move to iPadOS 15.4, there’s no going back to your current version of iPadOS.
