I have a Chromecast, Chromecast Audio and third party Chromecast speaker at home. They used to work quite reliably, with the occasional issue (mostly Netflix and Spotify losing connection).
Now, every time I use Chromecast I have to restart the wifi on my phone, restart the Chromecast and/or the app I'm using loses connection/crashes.
I have frequent problems with the spotify app on Android where I have to reboot the app in order for the cast or volume request to be received. On the other hand I barely have any issues with the youtube app.
Perhaps it comes down to the development of the individual apps themselves?
This happens to me regularly also. I either have to restart Wifi on my phone or reboot the Chromecast. Sometimes I have to reset the Chromecast. That said, I've noticed recently that it sometimes is device-specific and if I switch to my iPad it works fine, so it might not always be a hardware issue
I'm also having similar issues, but I wouldn't say it's getting worse. I've always had these issues. Google sucks about giving any kind of support, too.
I just bought a used PC that I plan to replace my Chromecast with.
Try completely rebooting (power off/on) your router. I remember hearing about a bug in the way Chromecast works that can cause buffer overflows in some wireless routers.
