Uninstall and reinstall app (sign in again)
It's hardly ever worked for me. The last thing I want is my phone binging any more than it does already.
I really can not tell you anything about the App as I dont use it, but could it be anything to do with there being a new one?
Please try un installing and then install the new version, please see this thread
