Re: How can I report my cheating team mate?

Access your inventory and click on the squad tab. Below you teammates name you sill see a few icons. Click on the report icon and select a reason for reporting them.

Alternatively use the link to report players for cheating https://www.easy.ac/en-us/support/apexlegends/contact/report/

Or this link for harassment and stuff like that https://help.ea.com/en-us/help/faq/report-players-for-cheating-abuse-and-harassment/
