Hi @Filipp. Welcome to Forums. This is Juan here from Zwift. I understand how essential it is for your to get you Kickr up and working with the Zwift Play to enjoy the virtual shifting feature.
I see that you contacted us and the model of your Kickr is V5. As you’ve already figured out, the firmware update for this model has not been released. I’d like to suggest you stay tuned on Wahoo firmware notes release for Kickr V5.
On the other hand, we have enthusiastic community members waiting for it. You can also periodically check other threads for updates from our community. I think this thread might be more suitable for you. Take Care!
