I get "Some data in My Library could not be downloaded. It may have been saved with a newer version of Zotero." whenever I try to synchronize the iPhone app.

I was able to remove some of the synch issues by removing new fields that did not exist before the most recent Zotero update from some items in my desktop app but it is quite exhausting finding these manually.
