Just downloaded the app having connected my Viewranger account. VERY unimpressed so far - no access to my OS map tiles within the app and very difficult to see how to use any features. Not at all intuitive and I'm not sure I shall be persevering. It might have been better to upgrade Viewranger and drop OA rather than the other way round. (Update) Zero*s. Provided some specifics to OA support, none yet been addressed. In spite of all the feedback, VR now switched off, leaving users stranded.
