[Heavy-matill]

You are right. I completely forgot that the Ids are not unique like UUIDs and also not synced to a global mobilesheets server.

Thank you for looking into this. I will try again, when the File date is supported.

Ah, I understand now. Annotation(Base) are linked to Songs with a specific page x. So they will be displayed independet from whatever file is displayed on page x for the Song.

Thanks for your help!
