Hi,
I gave the solution on this thread, and for them it works, https://colorlibsupport.com/t/team-section-on-portrait-view-not-as-i-want-to-see/ can you make sure add that in Appearance -> Customize -> Additional CSS, and make sure clear your cache and see that in a mobile browser or resize the browser window and see that?
Let us know,
Thanks,
