I have my half fare card on my SBB app. It shows I have the half fare card valid starting next week. When I put in a route after my pass becomes valid I get a certain price; however, if I use the date prior to my pass being valid, I still get the same price.
Is it not calculating my half fare rate, though everything I read says it should. Maybe it always calculates the half fare since it's saved in the app, but then you need to show it when requested and it should have valid applicable dates?
