Hi Brent,
I also have this problem (Certificated not installed), and i’ve re-installed certificates and profiles several times, and everything seems to be ok but still “certificated not installed” in the build screen.
I could try to update Corona to #2393a but before it i wanted to build some apps which are in previous version (1202) and i built them for android and published at google play. It would be a lot of code changing to update them to 2393.
My question is, is there any other way solve this issue? maybe with a lower version of Xcode?
Thanks in advance.
