Lack of storage?
Unless you are trying to make this iPad mini 6 store multiple iPadOS games, a lot of download music and video you have plenty of storage for a casual user with many apps, and usually most streams/reads content online. At ~ 40 GB free currently with everything copied over. 64 GB is more then enough for me to use the camera a bit, take short videos, or download a few movies for a trip. Then you can offload it to USB-C storage if you need to.
I should note some might really want to use the Mini 6 for serious content editing, managing collection, and that can use a lot more storage.
Now about that other topic, do you ever scroll in a way that you use your finger across the screen to stop the stroll quicker on a 60 Hz screen, I do. I don't normally scroll lifting my finger away. I haven't change how I scroll the iPad Mini 6 from previously Mini 5 either.
BTW This Mini 6 really pairs well with someone that uses a laptop or desktop, and also a smaller iPhone such as the iPhone 13 mini. I hope you can take time to play with it more sometime and use it differently.
