These last days I have tried to build a few routes around Switzerland on my laptop via the website. Sometimes this has worked, but oftentimes I could not not change the route. Whenever I tried to drag it somewhere or add a new via point, nothing would happen for a moment and then the popup 'Sorry, a server error occurred. Please try again later.' would appear.

This is hit and miss: sometimes cycle.travel works, sometimes it does not. At present it does not work again, and I have tried different routes, so it appears not to be route-specific.

As minimal working example, this is the route I just tried to alter when I got the error: https://cycle.travel/map/journey/1063379

Any advice would be great as I start a tour tomorrow and still need to make a few adjustments before leaving behind my laptop. Thank you
