AirPods pro
i recently got a replacement right earbud for my airpod pros the left earbuds version is 4A400 and the right is 4A402 and I think it’s for that reason they won’t connect together I’ve read a lot of trouble shooting and implement it although nothing has worked I’ve been trying to update one airpod though it won’t update and it’s only one airpod In the case what do I do ?
