Older Chromecast devices stop working, causing user frustration

Some older Chromecast devices, specifically the 2nd generation and Chromecast Audio, are displaying error messages and have stopped working. Users report seeing an "Untrusted device" error when trying to cast content, which may be due to outdated firmware. This issue began on March 9 and appears to affect users globally. Newer Chromecast models, like the 3rd generation and Ultra, are not impacted. Google has not officially addressed the problem, but customer support reportedly acknowledged it and stated that a fix is in progress. Users are expressing frustration online, demanding refunds and accusing Google of creating unnecessary electronic waste. When Google discontinued the Chromecast line in August 2023, it promised continued updates but did not clarify support for older models.
