I signed up for beta TestFlight notifications previously and I’m now trying to unsubscribe from these emails and having trouble. In the email, there is an unsubscribe link at the bottom, which brings up an email template (mailto:ios-beta@plex.tv?Subject=Unsubscribe).
Sending an email to this address keeps being sent back with the message below. I’m sending the email from the same address that the email is being sent to. Can someone please assist?
