Hello! I have an issue with stava authorization. And it seems to me that the problem is in Network layer -> Alamofire.
Inside
oauthRequest(Router.token(code: code))?.responseStrava
I always receive 401 Unauthorized

But when I use a simple base URLSession request with the same params, like in your Router, everything is OK and auth succeeds.

I can provide more information if needed.

Can you check please on your side and confirm that auth fails?

Thanks.
