You have several modes, the first is to add a comment, the second is to select something to add a comment to it, for simplicity you can select a group by selecting it in order to add a comment to the group, and simply click on the nested layer to bind the comment to this layer
now the situation looks like this: with the ungroup option all comment bindings are lost, also if an option is added to the layout and so on, this is very inconvenient, it is not possible to use comments in conjunction with groups and autolayout, and everything is built on this…
binding a comment to a group without selecting a group is an incorrect binding
