I had an issue after the Sense6 Sprint update, where Google+ wouldn't back up my photos. Finally figured out that the update had set my home wifi as a mobile hotspot for some reason, and wouldn't let some apps upload data over a mobile hotspot. Including Google+.
Oh and I am constantly getting reminders for voicemails, really old ones. Listening to them does not get rid of the reminders, had to go delete all the voicemail.
