I am still seeing the copy and paste issue I noted in the previous beta release:
I am unable to copy and paste more than two lines in the latest beta version Windows app. I will highlight and copy several lines but only the first two will paste if they are not on the same level (i.e. first parent and its first child will copy. Any subsequent children or any later outdented items will not copy). I can copy more than two if within the same level (i.e. all the children within a single parent item).
This is not an issue in the stable version or on the web app. I know this worked before Beta Update 1669365654967 because I routinely copied and pasted multiple lines every day. Even if the parent was collapsed it copied over all the children.
