Wife's phone will not connect for bluetooth key

We just picked up our R1S yesterday, and for whatever reason when we try to assign my wife's phone to her driver profile key, it will not connect. Her phone is grayed out on my phone's app, and her phone icon on the driver and key page shows a yellow exclamation mark on top of her phone icon. Any idea how to connect her phone?

We've already tried hard reset, soft reset, turning her phone on and off, forgetting the car from her bluetooth and reconnecting, and deleting the Rivian app and reinstalling it. Nothing works.

My phone (owner profile) works flawlessly. We both have iphones, mine's iphone pro max 15, hers iphone pro max 16 if this info helps.
