Thanks!
Maybe I'm doing something wrong here.
Can we back up?
After debugging and making sure the app runs on my iPhone, here is what I'm doing:
(1) Tools --> Build Server --> Build Release app
(2) Tools --> Build Server --> Download last build
(3) I now see the following in my Objects folder:
Folder: b4xlibs
Folder: bin
Folder: src
File: CalcMaterials.ipa
File: tmp.zip (contains folder: Payload, which contains 2 folders: CalcMaterials.app and CalcMaterials.app.dSYM)
(4) When I try to Upload App to iTunes Connect...
(a) Pointing to the CalcMaterials.ipa file, I get this message: "Uploading ipa file... submitting app... error: requires a top-level directory named Payload, containing only a .app bundle and optional plugins in a Plugins directory.\"
(b) Pointing to the tmp.zip file, I get this message: "invalid archive".
