iOS 26.0.1 (16pm & 13pm) rejecting calls by pressing side button twice is not working, I tested it on latest iOS 18 and it works.

Both my iPhones have iOS 26.0.1, and I tried multiple times to reject a call by pressing side button twice but it didn’t work

I tested my wife’s iPhone 13pm on latest iOS 18 and it worked fine.

Did you face the same issue?
