Hi ​@Ado, it seems that it's missing on your screen for some reason. Do you have the latest version of the app installed?

Anyway, as a workaround, you should be able to change the units via the web interface at https://www.strava.com/settings/display

current version 410.11 .  Infnix zero 30 5g . Android 13 

I see that there is a significant difference between the interface.thanks for your help
