Hi ​@daniscross, I’ve just tried but the map displays correctly for me (using Chrome on iOS, screenshot below). 

Does this happen even if you temporarily disable all browser add-ons, ad-blockers etc? If so, it would help if you share the exact steps to reproduce. 
 

Happening on the mobile (Android) app as well, but again, not for every activity with a 3D map. Cleared cache, force closed etc. very intermittent 

The same issue happens on mobile, too. Albeit, quite intermittently. Most activities with 3D terrain display correctly, but I’d say 25% don’t.

Tried clearing cache, using different devices, connections etc. I reckon it’s a Strava CDN issue.

Hello Everyone,

Our team is aware of this issue and currently working on correcting this.
I’ll provide an update when I receive more word to the team.

It’s visible for me on Strava app … when u share it on Instagram the 3D map disappears n just the route is seen.

Any closer to fixing this?
