Zwift website. American flag, German text. I’m in the UK, always have been.
You have probably followed an event link with the German language code, see Logged into Zwift.com this morning and it's all in French
To get it back to America talk, follow an event link that ends with ?__znl=en-us, e.g. FZR Pre-Sauna ride
Voila thank you!
Sorry but it seems to have forced your typing into French!
