How can I look back to see when I achieved each up-level?
You should be able to see that in your activity feed on zwift.com or probably in the companion app too. You’ll need to scroll through them all and look for the ones with the present icon, I think, that tells you you leveled up.
You might also find it in the Weekly Zwift Emails.
It says “Level Up!”:
But you only see it when you actually view the activity itself. It’s not shown in the list:
Not on Android, anyway.
Unless you’ve opted out or deleted after reading…
But yes, searching for “YOU LEVELED UP!” should show them.
The information on Zwift.com is NOT very helpful.
A few more details would be nice. They have the data. Why can’t they show what it is?
Scrolling through the website and the companion app, no level information is available prior to October 2018. I’m also missing level ups information between February and November of 2019.
