Hi - We are staying in Montreux (zone 73) amd would be spending all of today exploring Montreux and vevey(zone 72). Want to know how to buy a day pass for unlimited travel across these 2 zones. The app keeps showing up day pass for one zone by default, which i have infact bought by mistake for 8.6 chf. There is no option to select 2 zones for the day pass. (Although i did see the price for the same on their website at 9.3 chf)
