Google prompt won't show up after I flashed my phone

2-Step enabled, and I keeped backup codes. This is what I did: - Before I flashed my phone, I logout my google account. - Then after I flashed my phone, I logged in google accout from my phone by using backup codes. - In [Google - Your devices page](https://myaccount.google.com/device-activity) I signed out old devices. But when I checked the [Google prompts page](https://myaccount.google.com/two-step-verification/prompt) , it still showed my old phone(the name is the old one). And when I tried to log in somewhere, the "Google prompt" didn't pop up. I have to use backup codes or Authenticator. **Is there a way that I can fix this? or just disable "Google prompt"?** I'm OK with using Authenticator and backup codes when phone is not available.
