My Android app currently has connection problem (can't connect to server) with some APN when the APN protocol is "IPv4/IPv6":
- My app can't connect to my server
- Youtube, Google app still connect to Google server ok
After switching the protocol to "IPv4", every app worked fine.
I need to ask if there is any APN simulation that i can simulate many different APN profile to reproduce the error? (As my users are in a different country so is hard to get real device there).
