I believe what they’re getting at is an issue if they’re not already authenticated prior to the outage. Then they’d have no access to their media unless they look into the workaround for that beforehand. It has been an issue in the past, especially when Plex’s auth servers go down. I remember plenty of Reddit threads complaining about it.
I’ve had the Eros E3.5s for a few years and they’ve not let me down on quality, especially at the price point.
I also considered those Mackie’s.
