I have configured two appids in appIDs, but only the first one is valid and the second one is invalid, how can I fix it?
for example：
"appIDs": [ "ABCDE12345.com.example.app", "ABCDE12345.com.example.app2" ],
All are system functions, do you have any ideas to solve the crash?

Is there a way for iOS NSURLSession to control dns resolution by itself, similar to the ability of the libcurl library (https://curl.se/libcurl/c/CURLOPT_RESOLVE.html). Because I found that my app's domain name was hijacked in the public network.
