So, I am beta testing Zotero app on iOS. I am excited about Zotero's native coming to iOS!
Here's one issue I encountered so far: I open PDFs in Zotero on iPad and add highlights. Then synchronize them to Zotero storage (I subscribe) by pulling down. Then I try to synchronize Zotero app on my mac but it fails with the message that "some data could not be downloaded" https://www.zotero.org/support/kb/unknown_data_error When I remove the highlight from PDF on iPad I can synchronize Zotero on iPad and Zotero on my mac.
There is no error any more since I removed the highlight. I would need to reproduce it.
BTW, I have over 8000 items in my individual library and a dozen group libraries, I did not have any problems starting Zotero on iPad for the first time and synchronizing items.
