My iPhone 7 (iOS 14.3) will no longer make calls – audio nor video – over WiFi. I have tried re-installing WhatsApp and although it then asks me to grant permission to the microphone / camera / etc, it does not ask me for permission to use the Local Network.
I have checked Settings->Privacy->Local Network and WhatsApp does not appear in the list. Similarly if i look in Settings->WhatsApp, there is no setting for Local Network at all.
I have tried Reset the network settings, Reset all settings, and also just went through the Erase all content and settings. Following this I set the phone up again from scratch, downloaded WhatsApp and the situation is exactly the same.
Any ideas why WhatsApp wont use the Local Network? Other mobile devices on the same WiFi network work fine.
Confirmed that this error does not occur when my other iPhone (a 5S, connected to the same WiFi network) makes a WhatsApp voice call.
