Although Google devices are not prone to errors, there is always a first time for everything.
A bug in Chromecast causes the devices to disappear from the Google Home application. The error is causing the Assistant and Chromecast devices to disappear from the previously connected Google Home app. Separately they work well, but connecting it causes the problem.
As many social network users have reported, what happens is that Google Home does not recognize the devices and, therefore, it is not possible to send information from one device to another. However, there is one exception: YouTube. The video platform is capable of sending content to Chromecast through a voice command in Google Home, something really strange.
At the moment, there is no solution to this bug, so those who suffer from this problem will have to wait for Google to update the software and fix the error.
