A few days ago, I bought the full version of the Campercontact app for Android and it seems to be a really useful tool. However, when I try to download any offline maps, I get an error in the download immediately after pressing Yes to confirm the download. This happens for all offline maps. I have more than enough storage on both internal memory and my broadband is working fine. I've looked all over the campercontact website for help and tried to contact them but got no response. Anyone else use this and had similar issues?
