offline maps

Hello, i'm looking for a bit of help downloading some offline map. On the app, I'm clicking on little squares of Europe. Does anyone know where these are saved on my phone? And is it possible to download the same square more than once accidentally? Can a square no longer needed be un-downloaded and how would I do that? 

Thanks, Pippa

Navigation in app stops when I temporarily leave it.

Hello. I've been playing with the Android app in preparation for using it when touring. It's great and I've worked out how to do most things I want thanks to the Help bitty. However there's one thing I can't fathom out. I sometimes want to leave the navigation to check something else on my phone. I just minimise it but when I return the navigation has stopped and I have to load up my route again. Is there a way to get the app to run in the background please so this doesn't happen?

Rhine pdf maps

Hello, I'm soon to set off up the Rhine and am pleased to have discovered cycle.travel. As a map fanatic, and not wanting to either buy or carry all the maps that would be required, I was thrilled to see the 'download pdf map' facility. The Swiss section has worked, however the Dutch and N German sections will not open either on the website or in my android app. Have they not yet been produced?
