iCloud Sync Issue – PDF is Shared but Annotations Are Not

Hello, I’m a user of MarginNote 4.

As far as I know, PDF files in the Document - iCloud folder can be shared across devices.

For example, I use two iPads. When I annotate a PDF file stored in the iCloud folder on iPad A, and then open it on iPad B, I can see that the PDF file itself is shared—but the annotations are not.

Is this a bug? Or is it normal that annotations are not synced?

I’m a beginner, so I have many questions.

Thank you!

Hello, MN needs to synchronize a large amount of content with complex structures, which may result in a certain time difference between devices. Please be assured that we are working diligently to improve this!
