I encountered an issue while linking my email to my Towns account. I received the verification code via email, but after entering it on the Towns website, I get an error: “issue verifying code”, and the email is not linked. I requested new codes for the same email, but that didn’t help. I also tried using a different email, but the issue persisted. The codes are 100% correct. 
I found a solution to this issue—relogging into my account helped and I successfully linked my email
That’s right it’s works
