Packet Loss while playing Apex Anti-Ddos server

I am a new customer for Xfinity and I am experiencing a issue when playing Apex Legends ranked online. I am on Xbox, I have tried numerous troubleshooting options and I am at the point where I feel like software support should  step in. The best way to explain my issue is I have a perfectly experience until I play this game specifically . I have already did everything recommended in other posts on forum and nothing is working.
