Update…… if you have an iPhone and an iPad you have to do it on both

Has anyone from apple responded to any of these threads? It seems like they are ignoring these issues

My iPhone 12 Pro Max worked great with CarPlay and my Bluetooth accessories before ios15 now I have no sound in CarPlay and every time I want to listen using my new speakers I get a message that says I have to forget them and then I have to re-add them. Very frustrating
