Just got a new 16 Pro and set it up Monday 11/20. It was on 18.1 and everything worked fine. I accidentally updated to 18.1.1 (didn't turn off auto update) 12/2 and now Carplay doesn't work. I have to use a cord in my car for carplay. I have tried all the suggestions listed online and nothing works. I tried to erase my iPhone to go back to 18.1 but in the set up process it showed updated to 18.1.1 with no option to refuse. Incredibly frustrating and so many others have this issue! How was this not caught during beta testing???? This post was rejected from the apple forum and they sent an email saying it contained beta information. 18.1.1 shouldn't be considered beta and if it is then why was it pushed out to my phone? I didn't want a beta testing!
