Using iPhone 13 Pro Max iOS 16.5.1 I have restarted my iPhone and also deleted and re added voyager to my Home Screen. The webpage in safari works but the Home Screen app shows “Safari can’t open the page because it couldn’t establish a secure connection to the server.”
Works fine here, even after killing the app and starting it again. iPhone 13, iOS 16.5.1 © (20F770750d)
