Whatsapp can't connect through proxy.

[alcatraz-zz]

Hey everyone

I'm trying to help a friend getting xray to work on his iphone. He's using the latest Shadowrocket version and has geolite2 assets correctly installed and updated.

We still can't get Whatsapp to reliably connect through the proxy. It seems that UDP relay is broken for Xray at the moment. On my android phone it works fine but not with Shadowrocket.

I know it's not a problem with routing because I tested "Run all traffic through Proxy" and "Config" mode and it makes no difference.

Disabling UDP relay didn't seem to make much difference when I tried it. Furthermore, shouldn't it be enabled? UDP is important. Disabling it will maybe cause problems for other apps.

Do you have any tips for my friend? Will there be an updated Shadowrocket version with working Whatsapp support? (UDP?)
Thank you!
