I experienced this banging noise on Beyond in an IV cabin, 7161, in November 2022. I reported it on these boards. We sailed Apex, IV cabin 7231, in November of 2023 and experienced no noise issues. We’ve also sailed Edge several times in IV cabins with no noise issues. This leads me to believe the Edge and Apex don’t suffer (at least to the extent) from the noise issues that Beyond does. That worries me about subsequent builds. We are sailing soon on Beyond in a Sunset Veranda and I haven’t heard reports of these aft cabins being affected. I’ll report if our cabin does.
