I don’t think that’s my issue. I’ve used the setting “connect when last connected to” to avoid those inadvertent automatic switches. And while I have used it with my ipad or Mac, not so much this summer. I would get them working after a phone reboot, and maybe a half day to day later they would stop connecting until phone reboot. Today I reset the airpods, hopefully the connection sticks.

EDIT: I think I’m having a deeper problem with bluetooth on my iPhone. This page week I’ve also had to reset the connections on both cars. The only change I’ve made was starting to connect to my PC. Weird.
