Edit not appearing in public OSM public map

Thank you Fredrik. I did eventually see the footpath, but only at the highest zoom level on my PC. Strangely, the footpath is not visible on my Android smartphone. Perhaps they are rendered at a different time?

Incidentally, there is a blue dotted line where the previous (incorrect) footpath was shown. This still appears on the OSM map at any zoom level. However, it does not register as a feature on the map!

The blue dotted line will disappear when the tile on which it paints at that zoom level has been re-rendered.
A blue dotted line indicates a cycleway. Your corrected position maps it as a footway. A cycleway sign is clearly visible so you should remap as highway=cycleway and add foot=yes if pedestrians can use it too, unless the council has re-categorized it recently as a footway and removed the cycleway sign. The correct tags are need so that routing engines can work correctly.

Also see the answers to this question: I have made edits but they don't show up on the map .
