I couldn't add alternate email address to my account

I am unable to add my email address as an alternate email address and also unable to make alternate mail as primary mail. While trying for those actions, I’m receiving “Invalid Phone number” as an error.

Help me to solve this issue.

Open your profile, then click on the edit icon beside your name to update your phone number. Then come back to your profile and click on the My Settings gear icon to update your email ID.

Thank you soham, I changed my phone number, my phone number is starting with 6, I think this might be the reason for the error “Invalid phone number”. I tried with the number that is starting with 9, then it changed.
