I am attempting to make seat reservations from Frankfurt (Main) Hbf to Zermatt using the SBB Mobile app. When I tap Purchase Ticket I receive the following error:
Connection offers failed.
The offers must be reloaded with the selected role (B2C/B2B)
Error code: NTTIF-3006 (ID: D9JbgVA)
This occurs for whichever train I select for this route. Is this a temporary issue on the booking service, or a problem with this route in particular?
I am using an Interrail pass for the journey, and I cannot book the seat reservations alone on the sbb website until April 2024, so this is not a workaround I can use.
Any help would be much appreciated.
