Can't erase handwritings after changing iPad

Dear devs,

I changed to M1 iPad from old iPad 6th gen and all the migrated notes now have fixed handwritings.
I backed up Marginnote not with iCloud because of too little space left and I just “migrated” between iPads. To my surprise, iPad somehow magically transferred all my Marginnote data from the old iPad so I thought it was all set.

However, when tried to erase some handwritten ink on a migrated note, it was no longer possible to do so. My handwritings were just “fixed” on the document.

Is this an expected behavior? Is there any way to fix this ? (FYI, I already factory reset my old iPad)

Thanks devs.

Hello

Hello, you need to change to marginnote handwriting engine, or use lasso tool to select handwriting and delete it

Kind Regards,
