quick question - if someone was to test positive and had travelled on a train, would you get a ping through t+t only if you had the app on, or can they access reservation data?
I just got pinged, and will obviously isolate, but i'm trying ot work out what the cause was (mainly out of curiousity). 10 days takes me to sunday, where all i did was lie in bed, but i was supposed to travel back on the train (I left on monday morning instead).
