———————————————————————————
On both Firefox on a Mac and the app on Android, when I plan a route from the Netherlands to the UK, it is impossible to select the Hook van Holland to Harwich ferry crossing. I have tried double finger clicking on the ferry route on Firefox and a long press on android, but this merely results in a point being set in the middle of the sea. When I control click on Firefox, I get a large blank dialog in the middle of the screen. I have managed to get this to work previously, so it seems to be a regression.
