I sent a message describing this issue customer support. It was a longer message with details but concluded with:
“Both problems are described in detail on the forum and it would be really nice to have a response from Zwift and to know whether the change to the leaderboard was intentional or is a bug.”
The response I received was:
"I’m sure that the Zwift tech team are aware as it appears to be an issue affecting a number of users and it’s on the forums.
As an ambassador I don’t have the power to sort this, but hopefully it will be resolved soon.
Thanks again and Ride On."
My reply to that included:
“The reason I wrote here is to get some acknowledgment of the issue. No staff from the forum has acknowledged the thread (despite being asked); it has not been marked as a known issue so there is no reason to assume they know about it. Nor has any Zwift staff answered the direct question as to whether this is an intentional change or a bug.”
And concluded with:
“Your help in making sure this is properly communicated about to tech and back to users like myself is very much appreciated.”
I’ll keep my fingers crossed and let you know what I hear, but not feeling particularly hopefully as the response I got seemed crafted to primarily to disengage rather than to support and resolve.
