I lost my phone and my phone number but luckily my account was still logged in my iPad, so I went to my Google account in my iPad and I removed my old phone number and I added a new one. Somehow I got logged in my new phone. But The problem is that I can't do some changes on my account because it asking me everytime to verify that it's me with my old phone number. Knowing that old phone number doesn't exist in my Google account anymore, I changed it. Is this a bug from Google? What should I do?
