For me the new app is not satisfying what concerns the options of selecting maps. Especially the missing open cycle maps - OCM which was available in the old app is a big disadvantage.
OCM is offering much more details on trails, paths, especially in non urban areas compared to the TRAILS maps offered in the new app, In addition to this advantage it is also the visual style that is appreciated when using OCM.
Lets give a practical example. You are in a forest looking for a series of caches.
With OCM my experience was that OCM always could provide information on relevant walking or cycling paths to get finally to the cache. In such areas you cannot always choose the shortest direct way to the cache. You need a map with information on tracking paths to get to the target and to aboid dangerous situations.
OCM is a must for the new app. I paid for the old app which included OCM for online and offline use. So the new app should have as a minimum the features of the old one including OCM maps.
