Dorico for ipad - unable to make multiple selection of notes

I’ve looked at various tutorials etc… but can’t figure out how to select a group of notes in order to copy them.
On mac I would just rubberband them with a mouse and copy/paste or press r to repeat or whatever.
I see this being done on an ipad tutorial but I can’t figure out how to actually select all the notes.
I’m using a pencil (Apple2) and if I try and rubberband a selection - all that happens is the score just moves around with the pencil or finger.
How do I stop that?

You can also make a rubber-band selection on the iPad: touch and hold for a moment (around half a second) and you’ll see a little throbbing rectangle appear, which tells you that you can now make a marquee selection.
