Recently, I tried to create my first account in vercel to deploy my Next.js app. I choose log in with GitHub and next.js asked me to enter the phone number. So, I select my country Sri Lanka then, it said phone number verification doesn't support my country. Now, I tried logging in with email. So, I entered my email, then it asked me for OTP. I waited for it, but the OTP never didn't send to my email. Is anything wrong in next.js login system?
