And also alpha, lot of more bugs. Maybe in future releases get better, for me the website is best option for now

I have the same issue. It’s worse when the header is sliding in and out, but I have no idea what causes it. It’s not unusable though, just a bit laggy.

This has been a problem since forever. But it’s much better now.

I noticed this as well, it’s likely because the app is loading not enough posts to buffer for faster scrolling in both directions.

But I consider it a minor issue, if at all.
