Just wanted to mention I am also experiencing this issue. Hope it’s quickly resolved.
This has been fixed in Plex Media Server 1.5.4 that was released to public earlier today 
Thank you all for your patience while this was fixed and tested.
Thanks for your help in getting this resolved, @chrisallen. I’ve tested 1.5.4 and this fixes my issue.
Can confirm 1.5.4 fixes it for me as well.
Sorry I disappeared for awhile. Sounds like this may be fixed. Thanks @chrisallen
