@xavier221 thank you for that, but shouldn't it just work with the regular WhatsApp? It's data drive , I have a high speed unlimited data account. Proper network and good wifi signal.

@TP-Link I have not set any parental controls. Model of phone is IPhone 11 Pro, latest IOS 14.6 I think. I don't get an error message but the video call just does not get connected. It rings but as...

@MarkN @TP-Link_Deco Same problem whatsapp calls and video dont work. Deco M5, latest firmware. irritating.
