Changing email

I’ve changed my email address recently. I’ve tried updating my Plex account - & and it says the email is unavailable. I must have done something in the past to cause this, but the email is real and mine. How do I get it changed?

You probably created a second plex.tv account with this email address.
Even if you already deleted this plex.tv account, the email address is being marked as ‘unavailable’ for the next 30 days.
