I see episodes for all seasons on Streamio Android. For season 1 and 2, there are no streams though

Off topic question, I’m trying to learn about seedboxes: Do you have to configure your own VPN with your current seed box or is it not necessary?

That seems as a weird decision by Firefox considering their relatively privacy focused image.

What additional addon does Pimp My Streamio provide? I couldn’t find a list of their addons. Is it worth the hassle as I only use Streamio on Android.

Streamio with Torrentio add on + a Debrid service is all you need.
