After Loading Tor Box I noticed that the Torrentio Addon was not working (would not appear as a streaming source for a selected program and the addon configuration button disappeared). Up to then I had no issues with the Torrentio addon. I found that as soon as I turned off my Express VPN Torrentio addon worked as advertised then turned on the VPN back on again, Torrentio then stopped working. This occurs on all my devices running Stremio including my PC.I have removed, re-installed Stremio, Torbox, ExpressVPN plus a factory reset of one of my devices (NVIDIA Shield) and I am still getting the same result - no Torrentio whilst the Express VPN is connected.
This issue only affects the Torrentio Addon it does not affect the other addons I have installed.
