We have an existing app and we would like to add an additional privacy policy URL. So, there will be two policy URLs for the app. Is that possible? If yes, how to add the second privacy policy URL?

I try to connect to websocket server and send some messages, using NSURLSessionWebSocketTask.
Here is my demo code. This code works well on iOS 13. The Xcode that I uses is Version 12.0 beta 2 (12A6163b)
But the websocket is disconnected automatically (with the close code of NSURLSessionWebSocketCloseCodeProtocolError = 1002) a few seconds after the connection is created on iOS 14 beta2.
If I send short messages (e.g the message length < 10), iOS 14 beta2 might have much better chance to keep the websocket connection

The app clip is limited to 10MB. During the development, how I could know if my bundle is bigger than this limit?
The following code can connect to the host successfully on iOS Simulator. But the code fails to connect on an iOS device. I has checked the WLAN and Cellular Data are both allowed for the app clip.
I also try NSURLSession to access to a web site. NSURLSession is successful to get the data on both iOS simulator and iOS devices.
Do we allow to use socket streams in App Clips?
Xcode Version 12.0 beta (12A6159)
iOS 14 Beta: 14.0
But the code fails to connect on
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
//create socket connection
CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)@"www.baidu.com", 443, &readStream, &writeStream);
NSInputStream* inputStream = (__bridge_transfer NSInputStream*)readStream;
NSOutputStream* outputStream = (__bridge_transfer NSOutputStream*)writeStream;
[inputStream setProperty:NSStreamSocketSecurityLevelNegotiatedSSL
forKey:NSStreamSocketSecurityLevelKey];
// and open the streams
[inputStream open];
[outputStream open];
Console output:
