I am using a gen 1 google chromecast. I use to be able to cast from my pc to the chrome cast but now getting the casting available for specific sites message.
I found a old reply from a user that said this works but I assume this is a different gen of device cause I can't find these options on the gen 1
Here is below -
Old thread I know but hopefully I can help someone with SEO. I was having the same issue on my Chromecast dongle; to fix it I went to:
Settings > System > Storage > Internal Shared Storage > click on Cached data
And cleared cached data when prompted. Then I went back to Storage and clicked on
Apps > Manage Updates > See available updates
Which brings up a new menu. Then I went to
On this device > Chromecast built-in > click on Uninstall Updates
This fixed the issue (wow a lot of menus). Hope this can help someone
