The air cast icon on the app keeps disappearing

The air cast icon on the app keeps disappearing. When I switch from smart tv on my Roku to regular tv and back, I find that I can’t play YouTube TV again. I called once to customer service and the guy told me to uninstall and reinstall which works but then I end up having to do it everyday and each time I watch stuff on the app. This is very annoying! there should be a better and permanent fix for this. I’m not having this problem with the regular YouTube app... the air cast icon is always there, but not on the YouTube TV app ?
