Rivian Patent - Charging Algorithm - May explain why owners have different charge rate experiences

I have previously used the streaming capability back when it first came out as well as the hotspot since before Connect+ was a thing. I am trying to get the streaming working again but it seems to have been hidden fully behind the paywall. (Not looking to argue the merits of that system here) I recall after Connect+ came out being able to still use the Hotspot while tethering with my phone, and losing it isn't a big deal other than needing to update my wife's wifi, but I think I remember needing to be on the Hotspot to do casting. My question is, did Rivian remove both of these features to fully behind the connect+ paywall? I thought that if you used phone tethering or if you were connected to WIFI you could use most all of the usual streaming like features of the Rivian? If anyone can recommend how to stream while using tethering I'm sure myself and others without Connect+ would appreciate it.

There has been a fair amount of discussion regarding L3 charging where different users see different charge rates with no clear explanation. This patent application was filed in July 2023, so it's possible (likely?) that this algorithm is used in our vehicles.

It uses temperature, voltage and current sensors via a mathematical derivation to predict an overheating situation and cut charge rate preemptively. It specifically says that the algorithm can adjust based on new data collected.
