Imported PDF appears blank on the other device

Hello Notewise Support,

I am experiencing a synchronization issue between Notewise on my iPad mini and my Samsung Galaxy S24 Ultra.

When I import a PDF into Notewise on my iPad, the document displays correctly on the iPad, but after synchronization it appears as a blank document on the Android device.

The same issue also happens in the opposite direction: when I import a PDF on Android, it displays correctly there, but appears blank on the iPad.

The document itself, including its title and pages, seems to synchronize, but the PDF content is visible only on the device where it was originally imported.

I have already tried exporting the PDF from Goodnotes as a flattened PDF, importing it manually from the Files app, restarting Notewise, and waiting for cloud synchronization to complete. Both devices are signed in to the same Notewise account.

Could you please help me understand whether this is a known issue with cross-platform PDF synchronization? Please let me know if you need diagnostic data, screen recordings, or a sample PDF.

Thank you
