Rokukast from browser extension no longer works on streaming stick model 3800r. I have 2, both have same problem. Did work well until recently. What changed? How do we fix it?
Roku operating software version 10.5 is gradually rolling out right now. Check your Roku version via Roku menu path Settings > System > About.
Possibly the Rokukast browser extension needs to be updated for Roku 10.5, or maybe for the latest version of your browser. Check with your Rokukast installation/download source to be sure you have the latest version.
