Wrong serial number was registered
I just got my Roku Streaming Stick 4K and connected it to my Roku account. I tried to register for the "free HDMI extender" but I was given an error message reporting that the serial number I entered was invalid!
The serial number that I entered was copied/pasted from my "Device Details" for the Roku Streaming Stick 4K I just added to my Roku account. This is the same serial number that shows up when I go to the "System - About - System Info" section in the Roku system settings on my Stick!
I then disconnected my Roku Stick and looked at the back of it and the serial number printed on there was completely different! I entered this number in the page requesting the "free HDMI extender" and it was accepted.
I don't know what's going on with Roku, but why does my Stick have TWO different serial numbers? One that is physically printed on the back of the stick (VALID) and one that shows up in the settings (INVALID)? Roku needs to get their act together because this error just wreaks of incompetence by the people manufacturing the Rokus!
Anyone having a problem with their serial number being described as invalid make sure you disconnect your Stick from your TV and look for the serial number printed on it. I guarantee it will be different than the serial number showing up in your device settings on your Roku account. The serial number printed on the sick will be the 'valid' serial number! The serial number you are getting digitally in your account settings is junk!
