Refund for NowTV since it hasn't worked with my newer LG TV

I have a 2025 LG OLED TV and went to streaming services in part because Xfinity and LG should work together. The error code is TVAPP-00195, "This package is not yet available on this device." They never have after hours being on the phone with Xfinity. I was eventually told this was an outage and it should be resolved in days. It never was. I've cancelled NowTV and will ask for a refund.
