Not just the website, but also the mobile app, which users can use to check schedules, sometimes refuses to work. De Lijn declares that it is investigating the issue, but that it will take time. The company is talking about an 'unstable interface' in the site and the app.
De Lijn recommends using Google Maps if their own site isn't working. Google Maps also shows De Lijn's routes and timetables under the Public Transport tab.
