I try to notarize an installer for audioplugins (au and vst3)
Both plugins are signed and according. And the signing is succesfull ( checked with Terminal command "codesign --verify -v"
Same is for the installer, it is signed as well and the signing was succesfully checkt with terminal command "pkgutil --check-signature"
Still the notarization fails with the errormassages "The signature of the binary is invalid." and "The signature does not include a secure timestamp."
How can it be? And what to do against that?
