I want to unlock the ability to view content on my mobile device. I can do that with a one-time purchase (payed with google opinion rewards) or with a subscription. I want to unlock the ability for my entire family though, across multiple devices. Do I have to pay the “one-time payment” for every device? If so, the plex subscription might be worth it. Is there any other major benefit to having a plex subscription?
I haven't used Plex but Jellyfin is as easy as throwing this in Docker:

If you like Ansible and docker, check out saltbox. It’s a great project and if they don’t have what you need, it’s in community. They also use authelia sso. I’ve contributed to their community repo.
