Hi,
I have been paying for the NS Flex Weekend Voordeel for a long time, I have not travelled by train for about 2-3 months.
I have always bought my tickets via the Mijn NS app and all discounts were normally calculated for me as well as for those who travelled with me on the group ticket.
Today I wanted to buy tickets for tomorrow's train journey and in no way am I able to get the discount from the app.
Does anyone have any idea what to do about this?
