I have an LG TV with Fios One plus the new 3100g router. I just installed the First Cube. I set up the Fios skill. I can switch inputs, change volume and find shows on streaming networks. When I ask Alexa to change Fios channels I get the message that she cannot find ......... . The Cube installation automatically detected the LG tv. I am not sure it found the stb. In any event I have tried every suggestion posted here and on the Amazon site. Any suggestions? Thanks
