Update: Still getting builds rejected for invalid signature occasionally, but now the order is different. Build is uploaded, processed by Apple, submitted to TestFlight and then I get the nofitication of invalid signature. Additionally build is now marked as invalid in the activity tab.Previously build was uploaded and rejected during Apple processing. Build did not appear in the activity tab.

+1 Dealing with the same issue. No expired certs in the keychain, just the one App Store distribution cert. Random failures intermittently with the missing or invalid signature error.
