This thread is getting on a year old and I have similar issues with 100% of all my invites. I am not sure if even one of them have worked as intended.
So I finally figured out a work around for the link in the invite email error. This is what has to happen…
- The person who is receiving the invite MUST have Plex account set up first (this seems vital to the success)
- The Plex Admin sends an invite to a friend / family member.
- The invited guest IGNORES the email, but INSTEAD the email is the heads up for them to log into their Plex account / click on their Profile in the top right corner / Users & Sharing / Check to accept the invitation.
Only then was the invite successful and they were able to access my Plex library.
Until Plex fixes the email invitation link glitch…I hope this helps!
