I noticed that the Strava Global Heatmap layers (http://wiki.openstreetmap.org/wiki/Strava) and subsequently some of the OSM tools that use them aren’t working in some browsers (e.g. Chrome Version 58 on Windows 10). It still works for me on Firefox version 52. Is there an appropriate avenue to follow this up at Strava?
https://help.openstreetmap.org/questions/55267/strava-heatmap-does-not-appear-anymore may explain this.
Thank you for the the link. That is very helpful.
Thankfully, the Heatmap is working again.
