I saw this happen to me also. I got a fine for activating too late. When running onto a train to go skiing with full capacity and everyone coordinating things, I activated 3 minutes late. Still my easy ride receipt is with all the zones I travelled.
i noticed later that my receipt said I activated it 10minutes late. Luckily I have a screenshot on my phone with the time, and how long my ride had been on going which you can calculate to be 3 minutes. It’s also impossible that with the geolocation tagged station that it had been 19minutes. So either the train left 5minuted late and I wasn’t „late“ to activate, or there’s a problem with their ticket start time in receipts.
