Xfinity app not available for Onn TV Box

Unable to side load xfinity app onto Onn TV Box. And it’s not available in Google Play Store. Any suggestions?

This is the April 25 release. Xfinity Stream (Fire TV / Android TV)

Thanks. It loaded onto the Walmart Onn Box OK but is only streaming 10% of what I get on the Firestick Xfinity Stream app. (In particular I’m trying to get the History Channel). Not sure why?

Have you tried changing your VPN server location?
