I found a drag and drop issue in Thunkable X when rearranging the level of a component in the component hierarchy tree.
To reproduce the issue create or open an app such as this one described in this thread about a different issue. In this app a Drawer Navigator contains 3 screens. After collapsing all screens in the tree, drag
Screen3 (or the component at the bottom) and move it slightly up. You’ll see the INVISIBLE COMPONENTS tree move as matching
Screen3, which is instead supposed not to happen.
See what dragging
Screen3 looks like in the screenshot. I’m using an ASUS Chromebox with Chrome OS Stable, version 64.0.3282.190 as I write this.
