Every day I add the YouTube TV app to my Roku Home Screen. The next day, when I turn the TV on, the app is no longer there and must be re-added. This happens to NO other apps on my Home Screen
Do you have multiple Roku devices linked to your Roku account? Check the devices listed at https://my.roku.com after logging in with the email address displayed on your Roku device under Settings->System->About. Note that any channels/apps added/deleted from one device will get added/deleted from all devices linked to the same Roku account.
