Roku Device Features, Settings & Updates

Suddenly I cannot cast from Microsoft Edge or Google Chrome.  I had been doing it for years, but now on each browser I get "source not supported".  Is there a way around this, other than hook up an HDMI and not use Roku?

That's a Chromium/Chrome issue (happens on occasion with Chrome/Chromium updates) and Chromecast Protocol (aka Google Cast)/DIAL module issue (happens on occasion with Chromecast Built-in module updates on Android/Android TV devices).

For the record, it (loss of casting from Chrome) doesn't affect just Roku devices - it also happens with my WebOS LG TVs, Android/FireTV based devices, and everything else that accepts mirroring/casting etc.

You need to direct the issue/complaint to Google (or MS, for Edge, though of course its based on Chromium, so its best to go to Google with the issue).

So I took some time to test Chrome/Edge (older and latest release versions of each), and they are working as they ever did:  GCP/CCP (GoogleCast/ChromeCast Protocol) mirrors the (entire) desktop/tab/files to Chromecast Built-in devices (e.g. not Roku); otherwise DIAL Protocol sites (e.g. YouTube) cast (not mirrors) the tab to all DIAL compatible devices (e.g. Roku).

Try rebooting all your devices (PC, modem/router/gateway, Roku) and see if the DIAL casting (assuming from a YouTube tab) is working again.
