Hi all,

I have been using zotero on my MacBook and iPhone to do the readings. I understand I have limited storage in zotero so I constantly backed up and deleted the pdf files, hoping that I could have space to read the pdf on my iPhone. However, although I have storage space, I could not download the pdf on my iPhone, showing the error: "The attached file is not available in the online library. please check that the file has synced on the device where it was added." I could only open the pdf on my MacBook...

I have read other posts from the discussion board and checked that I have enabled "sync attachment files in My Library using Zotero". Could anyone advise what I should do so that I could read the pdf files on my iPhone as well? Thank you very much!
