Generally speaking the EndNote iPad app works great for me. However, over the past few days - since the most recent iPad software update I suspect - my annotated files become corrupted and unopenable when I sync them back to the desktop version of EndNote. I use a Mac (Sierra) and version 7.7.1 on my desktop. Any help fixing this issue would be greatly appreciated! So far it has resulted in several hours worth of lost work and anntotations.
