I had a similar experience using Organic Maps for hiking. I was hiking on a forested hill near an urban center. Both Google and Apple Maps only had a couple of the biggest trails while organic maps showed an extensive network. This was really helpful for exploring but I ended up having to take a pretty long detour to get back since the trail I had planned to take didn’t exist. I also encountered a trail marked on the map that had obviously been closed for years and was extremely overgrown. I really like the app but I wouldn’t trust the data for backcountry navigation at all.
