My son and his friend purchased the 6 day per month and under his friends app it says she has used all six days but only has 5 days of travel booked.  The 6th day which they haven’t booked is not on the app.   My son is doing the exact same trip and his app is correct with 5 days of travel and one free day.   They have updated the app and restarted the phone.  No change! Please advise as they are on a train right now. and thank you for your help.
