Problem with bluetooth

I have a 2024 Limited with JBL. I cancelled SiriusXM since I had it in another car and my phone. I use wireless Android Auto to get SXM in my Prius. Most of the time I start up the car, it connects to AA on my phone, and SXM plays automatically. Sometimes my Prius fails to connect to AA on my phone no matter how long I wait. To get it to work I have to go into settings and manually connect Bluetooth which shows disconnected. Once I click the Connect button, it connects, AA starts and SXM plays. Any idea why this happens and what I can do to fix it?
