I am trying to add a friend to my Plex Server but he is not receiving email invites. He is using email service that is based in Russia, list.ru. Is there any known issue when inviting people that are using this or similar email addresses?
Thank you for comming to my aid once more!
My friend has created account using the same email address and there was the invite waiting for him to accept. It was a bit clunky, not as simple when you recieve email but servicable.
Thank you so much for including the link that leads to user guide.
