Unable to setup 2-step authentication method

Hello ,
I would like to setup a 2 step authentication method .
I do have a verified phone number on my profile , but if I try to set it up .
I get the following error .
" no phone number available for method ‘phone’ "

It is a real number with network and not a Voip or google voice number .

I have tried using different browsers and also VPN to change the IP and i can straight log in into my account without any verification code .

This makes my account less secure .

Please assist .I have also made a support ticket .
Code: 3U18CC

Hello! Can you share a screenshot of this error?


Thanks for replying .
