Document annotated in 19 version cannot be opened in 21 version

I am working on a task where I have to update Groupdocs 19 version to 21, but I figure out that when I try to open a document annotated in a previous version it cannot be opened in the newer version, this is a problem the client wouldn’t be able to open their files unless I clean the annotation before, but this wouldn’t be good to the client because the document will lose all its annotations.
