We have completed our trip using the rail-app. All tickets for our group of 8 people are on my telephone. I now realize when I loose my phone we have no back-up. I thought of making print-screens and sent those to each member of the group. I don't know whether this is acceptable for inspection in the train. My question:
Is there a way to make an easy backup for all the trips I have created for our group?
Thanks for rely.
