No FaceTime audio on iPad over Wi-Fi after iOS 26 update

No FaceTime audio when using iPad over Wi-Fi after iOS 26 update. I followed all the troubleshooting steps I can find on the Internet, including resetting the network settings in both my iPad and my iPhone. My iPhone is routing calls to the iPad and I can see the caller, but I cannot hear the caller. Both my iPad and iPhone are signed into the same Apple ID, Bluetooth is off, Wi-Fi calling is on. I’ve tried disabling and enabling FaceTime. I’ve tried turning airplane mode on and off on both devices. I didn’t have this problem until the last two iOS 26 updates. iPhone SE, iPad Air, iOS 26.2.1
