Please add this feature which is available on PC and Mac already.
A feature in ZML across all platforms with this feature would help, too
I totally agree it would be nice to see this functionality in the iOS and AppleTV apps, as those are the versions I tend to use.
That being said I do remember when it was originally asked for in this forum it was mentioned by the Zwift employee who replied that it was a functionality already in place in the Mac and PC program just needing to be turn on for users. (I would guess it was a developer functionality originally.) As such I’m guessing that functionality was not built into the iOS and Apple TV and will need to be developed not just a toggle on switch like it was on Mac and PC.
