I’m just telling u what it does I plug it in it has a solid green light on and I can use it, I unplugg it light goes off I can’t get it to work! When it’s plugged in to the cord it works fine! That is what it is doing!!!!!!!!!
How long ago did you buy it? Where did you buy it from? If you purchased it within the last 12 months it’s under warranty from Roku., here is a link to start a warranty claim. So basically your remote only works when it’s plugged in as soon as you unplug it it will no longer work which means it’s not holding a charge.
Where did you buy it from? Walmart? Target? If you just bought it today then go back to the store and exchange it. You did pair it correct? I own 3 Voice Remote Pros. Have had them for a year. Worked right out of the box. If I just bought something and the same day it wasn’t working the first thing I would do is go back to the store I bought it from
