I have shared my plex with several friends over the last year with no problems at all. Recently I changed my plex media server over to a new pc and started with a fresh install. I started noticing one of my "Friends" kept watching things that showed up in my activity log as my crowned user watching it rather than my friend. After looking more into it I noticed it only happens when he watches things on his iphone. When he watches from his appletv or roku it will show it as his friend name watching stuff. But when he watches anything from his iphone it says its my username watching it. So I called him up and asked him about it, he checked his iphone and it says rather than being logged in under his plex account, it shows him logged in as my username. I have never logged into plex from any device he owns or even from any of my devices at his house.
I have attempted to remove him and re-add him as a friend multiple times and the problem keeps occurring.
This is troublesome to me for multiple reasons. For one if plex is logging him in as me, he then has full control over my server and can delete files or libraries. Another issue is that he said along with being logged in as me he had full access to other friends that had shared their libraries with me. Those people would not be happy if they knew some random friend of mine that they don't know has access to their server.
Has anyone seen this happen before? If you have any ideas on how to resolve this I would greatly appreciate the help.
