The power zone colored graph at bottom of screen disappeared after upgrading to latest version (1.25.0 - the one I had to change out my obsolete MacBookPro that I used solely for Zwifting, for a newer iPad). Do I need to go somewhere to activate this helpful graph? Tried, but can’t find where.
Welcome to the forum.
The bottom onscreen menu bar has a icon to enable it. Or G on the keyboard.
