Hiya. Thanks for explaining: I see your reasoning. I think in this case the problem probably lies with the app you’re using. You should get in touch with its authors and point them at https://wiki.openstreetmap.org/wiki/Access_provisions_in_the_United_Kingdom so they can make sure their app parses those tags correctly.

Access tagging is a complex topic (because access law in the UK is frustratingly complex), and lots of people get it wrong, so don’t worry about it. For future edits, the wiki is a good place to check if you’re not sure about the precise meanings of OSM tags. :) Or just feel free to message me if you want a second opinion on something, I’m happy to help.

Thanks for taking the time to try and fix the situation here, and happy editing in future! :)
