I upgraded with latest app. When Go Flying is selected a message is displayed that says Navigation functionality will only work for 30mins at a time when running in trial mode. My immediate thought was that I was running a trial version. Logged out then back and still get the same message so still don't know. So, if I am running a trial version then there is a problem as I am logged in with a purchased licence. If not then the message is a bit disconcerting and should not be displayed when a purchased licence is being used..

Sorry Tim, my mistake, I thought I had the full option but it seems not.
All sorted by handing over the extra 30 quid

Cheers,
Ian
