Long press the beginning of a measure (or at any ‘beat’) and it should select, then tap for the end of the selection. If you need to modify your selection at an end, tap the beat where you want it to be ending.
Then long press the blue selection line for the menu (copy, cut etc.)
To paste, long press on a beat for the menu (sometimes I tap first to make sure I have the beat, then long press on it).
If you need to cancel the blue selection, long press on the blue line for the menu and choose Cancel Selection (otherwise you cannot start a new selection).
Also if you have a selection in the clipboard but want to make a new selection, you will need to long press (somewhere on the chart, for the menu to Clear Clipboard). Then you should be able to make a new selection.
