Connect account from steam with mobile

Hi there,

I write current ticket because I can't solved to connect into my account properly,

Bassicaly I access my account from Steam account and I start a game, then I try to log in with steam email in the app but seems to be another account, when I request my password for my email used for registration both Steam and mobile app, it's sending me a general user name, then I'm being confused I have 3 nicknames , one email , one account

How can I connect using the same email for all platforms ?

Please check my current account registered in forum, is my primary email for Steam account also !

Please help ! Thank you !
