Google fixes Chromecast authentication issues for older models

Google is addressing issues with second-generation Chromecast and Chromecast Audio devices that prevent users from casting content. Affected users see error messages about untrusted devices or authentication failures. The problem appears limited to older models, as newer Chromecast devices are not impacted. Users have attempted various fixes without success, leading to frustration on social media. A Google representative confirmed that a fix is being rolled out over the next few days. Users must keep their devices connected to receive the update. Factory resets may complicate the issue further.
