Don’t try to change tickets on this app – DB Navigator Review

The worst experience. We had first class tickets from Germany to Italy on an EC. Tried to change to an earlier train. Apparently the app allows to change “seats” to a different train, but not actual trains! So we ended up with seats on the earlier train and no actual train ticket. The app needs to be a lot more clear about such distinctions. The conductor could do nothing to help except sell us second set of tickets with no seats. Another problem - why can’t the app show us where free seats are so we can reserve seats. Even conductor’s app could not show free seats so we and luggage were tossed from seat to seat for the next three hours.
