For the last couple of months, I have had this issue of other aircraft being “unknown”.
This is not the only issue, the other issue is when I contact ATC, my messages are broadcast on my device, but I am never getting a reply off ATC, it’s also the same when they give me instructions.
This is all happening when I have a good internet connection, as you can see below.
My device : Huawei p9 lite
OS: Android 7.0
Infinite flight version: 18.01.0 (latest version)
