Have you checked that the weather model update was the same on your 2 devices ?
I made a test with the mobile app (iPad) for a trip between Gijón to Concarneau with a departure date tomorrow at 9:00

And same in the browser version

I do not see any discrepancy except the duration of the trip, one hour difference.
The update of the model was the same reference time 00Z.
