a rather curious thing happens to me, I have created a project with Unity, I have exported it to iOS and I have configured in XCode what is necessary for its compilation (Team, certificate, a parameter for hhtps in the info.plist, the version and the Store icon in 1024 x 1024).
I generated the Archive, which does it correctly and I have uploaded it to the Store without publishing, to do a test through TestFlight, but I had a failure and I had to upload a new build.
This same app works perfectly since I compile it without problem if I connect an iPad or an iPhone directly to the MAC and do a Run instead of an Archive.
The fact is that when I wanted to create a new build, I followed the same process, changing the number of Build and I uploaded it to the Store.
When in the iTunes Connect website I try to add the new build, sometimes (not always), I see the build as pending, but sooner or later it disappears and it is as if it did not exist, but in reality it is not, this is uploaded, because if I try to upload again using XCode, this gives me an error saying that the binary already exists.
I have tried both to change build and version, but nothing, there is no way to upload the modified app to send it to the testing team.
Any ideas?
A thousand thanks.
