Recently the Netflix app on my S22 Ultra stopped showing the Chromecast icon. I tried the steps in https://help.netflix.com/en/node/58351 and it did not resolve the problem. So, as a workaround, I installed Netflix on my Pixel 5, and right away the Chromecast icon was present in the Netflix app. Fast forward a few days, and the Pixel 5 based Netflix app also did not show the Chromecast icon. In both the Ultra and Pixel 5 cases, the Google Home app was always able to see/manage the Chromecast device.
Last night I chatted with Netflix support, and from that one step I may have missed earlier was checking for the Google Play Services update. On the Ultra, I searched in Settings for "Google Play System Update" and this returned a result for "About phone\Google Play system update". Clicking on that opens "Settings\Software information". Clicking on the "Google Play system update" then opens another page that checks for an update. Mine is on the April 1, 2023 version, and no updates were available when checked. I have always assumed (perhaps incorrectly now) that the Google Play system update would be automatically updated via the Google Play framework.
So, on a hunch I decided to reset the Chromecast. After resetting and joining back to WiFi network and verifying that the Chromecast was visible/manageable via the Google Home app, I opened up Netflix on the S22 Ultra, and the Chromecast icon was present, and I was able to cast to the Chromecast and its associated TV.
