Rivian Connect+ Requirement: Change in Policy or Glitch?

[Rivian Mom]

I've been using my phone's hotspot for months, and my Rivian connects to it automatically to run TuneIn and Spotify through the built-in apps on the main display. To be clear, this wasn’t Bluetooth streaming but actual phone data, and the apps worked perfectly without any issues.

In Monday for the first time, I saw a Connect+ message pop up, even though the truck was linked to my phone’s data.
I can still stream from my phone using Bluetooth, but the sound quality and user experience weren’t as good.

This issue started between over-the-air software updates, though it might be tied to a specific date in the system. I tried a soft reset, but nothing changed. Has anyone heard if Rivian changed their policy on this?

I remember Connect+ used to mention it provided "data" for streaming apps, suggesting you could use your own data instead. Now, it seems like you need Connect+ just to access the apps at all.
I was surprised they allowed phone hotspots to work before, so this might be a deliberate change.

I’m okay with paying for Connect+ if this isn’t just a temporary glitch. Any insights would be appreciated.
