A technical issue disrupted casting on some first-generation Chromecast devices earlier this week. Google confirmed the problem has been fixed and devices are now working again. The company said no permanent changes were made to the hardware.
Sahana Mysore, senior product manager for Google Home, stated that a technical issue temporarily disrupted casting for some Gen 1 Google Chromecast users. The team identified the root cause and resolved it quickly. All devices should be working now, with some users reporting restored function as of last night.
