Log says "Couldn't upload 22 pending files" How deal with this?

As soon as the Dropbox client app downloads missing/newer files the pending flags should be removed and therefore the message is not logged again but former logged messages should be still there as long as you didn’t restart the app or clear the log.

Sorry for another follow up to the above statement. If after an app restart (which would clear the original message) the pending condition still existed would it be logged again?

Only if the sync needs to upload the file.

Thank you, so that is further confirmation that the condition had resolved itself.
