ZwiftMap 2.1.9 fixes a problem with missing chat messages. Hopefully all messages should now be shown when you run ZwiftMap with the network capture features activated.

For macOS it should also improve the ride metrics display (that was fixed for Windows in the last version 2.1.8 but not for macOS).
Where can I get it?
Find the downloads and more information at the ZwiftMap page.
