Twitter verification on CoSo

now I must state this happened for most users here back in 2017/18 so it might not work anymore there are a few steps needed to do this ALL steps need to be done inside Chrome browser

srep1: if you are logged into Twitter and CoSo then log out

step2: now you have clear all Twitter data and CoSo data NOT just clearing cache you need to clear all data including site settings EVERYTHING needs to be clean for both sites data related

step3: open Twitter first log in

step4: open CoSo log in

step5; in your Twitter profile add your own PLP, public landing page, to the URL inside your profile

step6: refresh CoSo and see if your Twitter account has been verified(it might it a while so keep trying)

now like I said this method might not work BUT considering my Twitter account on my CoSo profile page still says it's verified I'd assume it will work
