Can navigation be turned off?

Hi. I have used the app since it first came out on android, but maybe not as intended. What I do is to create and save a route via the web page, then open it in the app so I get the blue line, but then have navigation 'off' and just check my location manually from time to time to ensure I'm still on-route (ie on the blue line). This used minimal battery, which is important on a multi-day cycle camping trip with little access to a mains socket. However, in the latest update I can't find a way to turn off navigation, nor to stop the app checking GPS in the background, whilst still having the blue line. This means that it is using noticeably more battery.  I have tried using the web page for on-route checking, instead of the app, but about 10% of the times I try to check, there is no internet access, which means I'm blind till I ride on to where there is. Any suggestions, please?
