How to erase handwriting from mn3 pencil kit?

i need to modify some memo but there’s no way.
and some documents don’t support switch document notebook.
plz help


I read from Chinese forum that MN4 now only support PencilKit, while MN3 don’t (only support PencilKit). Therefore, if you edit handwriting without PencilKit in MN3, it can’t be edited in MN4. The only solution offered is “Using MN3 instead of MN4”:nerd_face:

Hope my reply helps!
