I have an Insignia TV, and just use an OTA (over the air) antenna. The Smart Remote app has the correct code, and in fact turns on the TV just fine, and even enters the actual numbers correctly. However, it doesn't have the standard "dot" or "dash" input that you need to tune to digital channels. So, when I want to turn on CBS for example, which is channel 2.1 or 2-1, the app automatically puts in "21" which isn't a channel. Even the actual GUI remote does not have a dot or dash, so I can't even enter it manually. Any ideas on how to get this dot/dash to enter in?
