Roku Voice Remote Pro Stopped Working

I’m so tired of everybody saying to take the batteries out, the batteries are internal and can’t be changed out it’s a rechargeable remote, I’m sure  you have the same issue. I wish people would quit giving the same answer that is used for A remote with removable batteries. On the back of the rechargeable USB voice pro remote, you will see a black button just above it there’s a pinhole with tiny green light that will eventually flash, but you have to hold it a lot longer than five seconds. I held it for like 20 seconds and it came on so then I plugged in the Roku and went to the set up options and search for a new remote, and then I held the button until the green light continually flashed (less than five seconds now ) and then let go of the button and it found it. I don’t know why it became unpaired, but I did have it fully charged but Roku said it was only 86% charged. It works now
