This one doesn't seem to reproduce every time which is odd, even after adding connection and removing it. I can't currently reproduce it on device or simulator on iOS 16/17 (iPhone 13 (iOS 17.6) & iPhone 7+ (iOS 16.8.1) mentioned as reproduced in issue).

The current code is specifically disabling this already, too: https://github.com/brave/brave-core/blob/master/ios/brave-ios/Sources/BraveWallet/Settings/DappsSettings.swift#L166
