@OfTheWolf ok i will share the sample code. Basically in the bottom tabs i used tableview and when i reload tableview and scrolls it tableview moves to top (its insets changes)

I believe it's caused by updateOverlayScrollContentSize in ContainerViewController, but my fix still not perfect.

bottom tableview/scrollview content size changed(estimatedRowHeight tableView when scrolls to bottom, or load more) --> overlayScrollView content size change --> overlayScrollView scrolls --> bottom tableview/scrollview scrolls(here causes Scrolls to Top even if revert contentOffset.Y, and drag scroll gesture will be interrupted)

    private func updateOverlayScrollContentSize(with bottomView: UIView) {
        let contentOffsetY = overlayScrollView.contentOffset.y
        self.overlayScrollView.contentSize = getContentSize(for: bottomView)
        if contentOffsetY > 0 {
            // revert contentOffsetY after contentSize changes, but still not perfect
            self.overlayScrollView.setContentOffset(.init(x: 0, y: contentOffsetY), animated: false)
        }
    }

@hstdt @mohanthakur92 I'm having same issue, did you guys solve it?

When I use table view with static cell size everything works fine but when I use table view with dynamic cell size, the scrolling is lagging specially when scrolling up
