Can anyone confirm that they have been able to purchase the Swiss Half Fare card via the SBB.ch website? I have created the SwissPass account, logged in, added all of my information (and co-passengers), selected the Swiss Half Fare card, but when I select the continue to checkout, it throws an error stating that there is nothing in the basket, and it is unable to process the query. This has been going on for several days. I have tried it with both Chrome and MS Edge, same issue/error. I'm really surprised, as the Swiss train systems are usually very reliable, and I thought the websites might be as well. Is it just me, or have others had issues in the last few days trying to do the same thing? I'm logging in from US BTW.
Also, it does not appear that the Swiss Half Fare card can be purchased from the App. At least I have not been able to find where it can be purchased.
