We’ve been having problems with iTunes recently as we can’t sign into our account no matter what. We’ve reinstalled it, restarted the computer, reset the network, etc. and nothing has worked. We decided to message Apple Support about it and they checked to see what the problem was. They said that nothing was wrong with our account and so on, but that something on the computer was blocking us from signing in. Does anyone know how we can figure out what applications are blocking iTunes? This would be a massive help so I can uninstall them and hopefully get our account back in.
