Samsung TV and Gemini Air

As documented on multiple sites, Samsung TV and Gemini Air simply do NOT work together.  Got a new QN70F w/ Samsung soundbar (CEC/Anynet) and Gemini Air refuses to work properly whether routed to alternate HDMI In or through Soundbar.  Paired remote both automatically and manually.  All works great on 3 other TVs (2 Vizio, 1 LG).  Consensus is Samsung CEC is peculiar. Purchased CEC Blocker (pin 13 open) between GA and TV, but still a problem.  Remote controls OFF and VOL and all DTV functions but can not turn TV ON.  When TV turned ON with TV remote, still must turn on GA with its remote, and it reboots, sometimes turning off TV.  What is the incompatibility between Samsung and Gemini Air?  How can I resolve it?  This is apparently a well-known and long-standing problem, but I can find no solutions online.
