Hi @Port
Steve, @Steve_UK is correct.
When an edit is [internally] approved usually there is a temporary status on which the two lines lines are visible simultaneously. If you check the orange dotted line you will see that the starting point is no longer connected with the existing road.
The dotted line will disappear when you will receive the notification of the approval.
This is very normal, and I’ve observed it thousands of times on my own edit.
Hello @Port, that happened to me at least once. I was trying for quite a while to add a biking path. I was able to complete about 5 km or so in small pieces, but couldn’t finish the loop at the end:
Tried many times to complete the part inside the red marker, but all attempts were rejected. But suddenly, the entire loop was completed. I also believe, it was not another user, but Google finishing this.
Nevertheless the entire path with some 20 km in total, still has many gaps.
