I'm getting an error when I try to sync my iPad and PC. In the most recent case, I downloaded the item on my PC and I'm trying to sync it to my iPad and the error says "Some data in My Library could not be downloaded. It may have been saved with a newer version of Zotero." But there are no updates for my iPad app. This is my first time noticing this issue, but it says there are 20 issues.
