Hi @Martin13, sorry to hear that your MijnKPN app crashes.   We've seen several notifications from customers that the app only shows a white screen. There is a work around that will solve this problem for now untill an update of the app is released. Please go to Profiel - App instellingen and make sure Contacten is Uit. Contacten is an option that enables the app to make a connection with your contact list on your phone, the app will then show names instead of numbers in your app. We don't know why, but deactivating this option makes sure that the app will work again. Ofcourse we will try to run a fix in the next update for this.
