Okay, I now used a fresh GOS install to test InviziblePro on main and private spaces and it seems that it can not connect at all to the tor network anymore on the private space. I don't know if this has been a deliberate decision to fix a potential leak or by accident.
Maybe Final (nprofile…yg8t) can clarify.
I very much liked it to start tow separated Tor connections on the same device to logically separate app network use.
