Hi, no problem, we are here to answer all questions and to help all each other.
So the is not up-to-date but also the website is not 100% up-to-date. My personal tip is to check the website of the train company. In this case it is Eurostar.
If a train is missing, you can add it manually to the app. Please be avare that due to a bug in the iPhone version of the app, I do not recommend to do it with iPhone.
Please also check that for Eurostar there is a check in. You have to be at the station 40-60 Minutes before departure of the train. Due to corona rules check, it is better to be more than 60 Minutes before departure in London St. Pancras International. Please check more Information about this on Eurostar.com
Thank you Angelo - I will try to change the train time in the app - thankfully mine is Android
It may help to update your app. There was an update recently; the app version should be 23.3.0. Check under More and scroll to the bottom.
