Map issues with the london map

I’m having a problem with the London map on the Companion App, and it seems to only be the London map.
I can log on OK and the map works in Watopia but if I swap to a group ride in London all I get is a black screen with a line through the middle. It seems to works for all other maps except London?

Have you updated to both the latest version of the Zwift app and also the companion app?

Yes both latest version

What device are you using?

Windows 10pro on quad core AMD
Phone is a Doogee S40 Android 10

Sounds like a strange compatibility issue. Other than uninstalling the companion app and reinstalling it I’m not sure what else to suggest.

If that doesn’t work I’d submit a ticket.
