Strava laittoi myös route builderin uusiksi. Veloviewer-plugin ei enää toimi siellä, ja jatko näyttää epävarmalta

Sorry, I’m with you now. The Strava guys have loved me to the new version of the Route Builder and I’m really not sure I’m going to be able to overlay the tiles. The structure of the DOM objects and the way the objects are masked will possibly make it impossible to do it. I’m happy for someone to show me I’m wrong though!
