LTE Connection via ATT Spotty as Hell. Integrated Streaming via Apple Music Not Functional

[colgate]

Keep getting "problem with the network" errors, and Integrated Streaming just doesn't work. When I'm lucky I get 10 seconds on Apple Music, and it fucking drops. Search in SATNAV also spotty as fuck. Is this a common issue? Anyone from a different Lexus model know how to fix this?

I noticed the att is crap, is it the same that's used for the digital key and remote communication?
