Thank you so much for getting in touch!  Sadly you can't be emailed with attached drawings, so here goes: 
Yes indeed, our neighbours at Low Bridge End are getting really fed up of people traipsing through their Tea Garden (without stopping for tea) following their apps, as this is NOT a public right of way or a permissive path.  
I live opposite, at Fornside Farm, and I offered to help as we had the same problem with people using OS routes and also All Trails and Komoot ... editing the Open Street Map seemed to solve it for us.  However, I cannot seem to alter it successfully at Low Bridge End.  

From what I can see, the informal path from the gate past the Tea Garden should be marked as PRIVATE and not open to anyone either on foot or anything, and also the track across the river to the road should also be PRIVATE, it is not a public right of way or a permissive path.
