Unable to log into nest app in iPhone 15

[makrithambi]

I recently changed my iPhone and since then unable to log into the nest app on my iPhone. 

when I try to log in , the login takes me to google .com. Once I enter the user name and password , the process asks me to log into YouTube and confirm its me. 

Now , in you tube , when I try to log into the same user as nest, the login process takes be to google and then upon entering the password, asks me to sign into the YouTube and confirm its me. I reached this login page , while trying to sign into you tube.

This is ridiculous and looks like a chicken and egg situation. Switching to google for authentication for nest is a big mistake.

How to resolve this .

Hello makrithambi,

I'm sorry for the inconvenience you have experienced while trying to sign in to your account on your new phone. I'd be happy to take a look at this for you.

It appears that the prompt asks you for verification but loops you to an authenticated app installed on your phone. Can you try to sign in with "Sign in with Google" and/or "Sign in with Nest"? Depending on the option you haven't tried yet. Then, if it still asks you to verify your account, I'd suggest installing a Google app and signing in with the same credentials so it would route you to it. Also, in your phone's settings, make sure that the Nest app's permission is allowed.

Let me know how it goes.

Regards,
Mark
