Can't see other riders around me on IOS Companion

Hi I have just changed phones from Android to IOS and when I go into companion I can’t work out how to see other riders around me like I could on Android. How do I do this on the IOS companion app? Many thanks.

While riding, you can see other riders as blips on the Companion app map. You can also get a list of names like what you see in Zwift by selecting “Zwifters” on the bottom of the Companion app.
