Set up a new Apple TV 4k and did a Zwift ride - everything worked fine, right up to finishing the ride and checking the critical power data - and it did not have any of my old data to compare to, so the only graph I got was the one from this one ride. Is this a known issue? Will it affect future auto-FTP recalibration if prior rides are not remembered consistently?
Had the same problem when I upgraded my PC J. H.
All worked as it should but the ‘Ride Report’ screens at the end only showed data from the ride I had just finished.
I thought I had goofed up so didn’t report it.
May be worth an official ticket now.
As I remember it didn’t effect my FTP or the power-zones built around the FTP.
