Due to an update your documents will need to be converted. If your document needs this conversion we will show you some text and block you from ruining your document by editing it with SmartCite.
If you don't have access to the desktop version of word please reach out to our support team at support@papersapp.com and we can run the update for you and give you your doc back so that you can continue editing it on word online. This is a one time update that should make editing your docs easier in both word online and desktop and we apologize for the inconvenience.
