I have a TCL Roku TV and it updated to the latest OS 10 last night. Now my Harmony remote is have a ton of issues. But the main issue I have is that the "OK" button on my harmony remote does not work with Roku anymore. So I am unable to select anything at the moment making the remote useless. It has to be something with the new update because it was working fine yesterday. And I know the "OK" button still works because I tested it with my Xbox and it's works just fine. So the issue is somewhere with Roku and the new update.
I have re-sync the remote, rebooted the remote, and rebooted the TV multiple times.
