We are having the same issues with ALL 5 different Roku devices / TV's we have. After having the "Roku Support Known Don't Contact Us Anymore" issue of the YouTube TV app not working (09/14/2021), I too decided to uninstall the app as a means to a resolution. What a **bleep** mistake....... After doing so, now there is no YouTube TV app avail to download. A few hours ago Roku said that ISSUE was "fixed" however after "checking for updates (on ALL 5 devices), none of them reported any updates found to install. So now I (AND PROBABLY HUNDREDS OF OTHER USERS) can no longer get the **bleep** app at all. This is all BS from both Roku and Google. On Amazon now ordering 5 HD 4K FireSticks.
