Cannot login on iPhone App with Google account

I’ve recently switch from and Android phone to iPhone and I’m trying to login to the SmartThings app without success. Unfortunately when I set up my account I did it via Google sign in. Now I don’t have the option to login in the iOS app. When I try to login with my email address it says that I have to use the login with Google option which is not available. How can I fix that?

You can manage your account @

You can turn off Google account there


That worked, thank you!!
