Wedding wire for guests app problems

Hello,
I am having trouble signing into the wedding wire for guests app. I selected that I am the one getting married. I made my qedding wire account by signing in with google. There is no option to sign in with google for the wedding wire for guests app. I tried making an account thinking maybe it's not the same as wedding wire login. It said my email is already on an account. I tried to sign in with my Google password that didn't work. I tried reset password and the email I got only took me back to the wedding wire guests app sign in Pass. It didn't let me reset my password.
