Just yesterday, Zwift posted another update on the new home screen. The new home screen has been in the works for several months now, and it is still only available to some users. Zwift announced that they will be continuing the roll out of the new home screen to Android and iOS users. The roll out continued on August 17th, Wednesday.
Zwift has also informed users that they are working to get the new home screen to work on Apple TV. There are lots of sizing and scaling issues that Zwift is currently working through. Note that the current roll out is targeting tablets, so it will be more common among tablets than smartphones.
The Ride With feature will also be coming soon. Zwift is prioritizing the release, but they have noted that they will try to bring back the Ride With feature sometime in the fall.
