Very annoying that the app keeps reloading (from the internet) the tickets that should be cached locally. Makes for a sub-par experience when being controlled in the train and the connection is spotty. Also, it would be nice to have connection information in the app when we need to switch stations (for example between Montpellier St Roch and Montpellier Sud de France). It's annoying when you don't know the city and have to figure out the tram network or whatever.

Bonjour. Pourriez-vous nous donner un exemple de billet pour lequel vous faites ce constat (référence + nom) ? Merci d'avance pour votre retour à l'adresse Bonne fin de journée.

It includes random unnecessary amounts of time for waiting and boarding the train when planning the route. Often when I go through the process of buying a ticket on the app I get to the last step and the app glitches and I have to re-enter all my information. Unnecessary bus routes added and misses trains off the schedule. I have to filter the mode of transport each time, won't save preferences. The amount a delay displayed for a late train is often inaccurate, unreliable.

Bonjour. Serait-il possible de nous préciser le trajet concerné (gares de départ et d'arrivée, horaire et date) ? Lors de l'achat d'un billet TER, rencontrez-vous un problème ? Un message d'erreur s'affiche-t-il ? Est-ce que vous indiquez le code 3D Secure ? Merci pour votre réponse à l'adresse Belle journée.

This app updates quite fast and accurate the information. There was one time the platform was not displayed on big screen due to technical bug, but the app already updated. The visualisation is nice, simple but applicable. There's only one thing which I think should be improved. It takes long time to delete the ticket which you cancel so when I cancelled and bought another tickets, sometimes I got confused between two tickets for the same train, but different seats.
