@ibc I changed the format to urls array like you have mentioned, but it still did not work. and like I have said, I tested the TURN servers that I am trying to use with mediasoup, and they work perfectly fine.
Did you try connecting two devices on LTE when you added React Native to mediasoup-client library as a supported device? Did you pass the TURN servers like I did? Or did you also use different ways to implement WebRTC connection when devices are on LTE or 3G?
