Airpods ring but don't connect to call
So I've got a pair of regular degular airpods and when I'm walking around with them in my ears listening to spotify, I'll get a phone call, and the music stops and my airpods play my phone ring, all good.
But then I answer the call and the call audio goes to my phone earpiece. My music still isn't playing and I spend the first 10 seconds of any call wondering what is going on until I manually select to route the call to my airpods.
What's going on?
iPhone 13 Max (or whatever, 3 cameras), up to date iOS, regular airpods.
