Plex Share- Is what you are paying for by the month to get all the Content. Movies and Shows.

Plex Access- Or Pass is something the Plex App itself charges to use it's app on different devices.  It does not go to us, and has nothing to do with us. But if you need to use Plex on your Android Phone or iPhone or iPad or some other device other then the Softbox, you will need to pay $5 for that device to Plex so that you content will play more then 30 seconds.

You should need only to pay $5 one time for that one device. There is no need get the $5 a month subscription or lifetime subscription. --- Unless you are planning on using a lot of different devices.
