Thank you for your request.
As mentioned by @RolandP, it’s important to give us information about the itinerary and the day of travel so that we can test on our own.
In all cases, I recommend that you proceed as follows:
Delete the application data and the cache in the settings of your smartphone: «Settings» -> «Apps» -> «SBB Mobile» -> «Memory» -> «Delete data and empty cache»
This also resets the timetable-favourites and the touch-timetable in the SBB Mobile App.
I hope I’ve been able to help you. I wish you a nice weekend.
