Thanks Julien. This is a mildly annoying bug but doesn't actually break the functionality. But I am reassured that the mangement are interested in the ongoing future of PR and so very happy that the developers are prioritising an infrastructure update. Glad you are doing better.
Actually it would be pretty dysfunctional if working on long routes. When you refresh the browser (keeping url of editing route) the screen automatically rolls out to view full length of route requiring tedious (on desktop) recentring and zoom of area you are looking at. But mine are rarely >25km so it's negligible.
