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?

I installed iOS 16 on one of my devices to test my app on there. However in XCode it is shown as unsupported iOS version. And if I try to install the app through internal testing on TestFlight I get the massage that I have to activate the developer-mode. So how can I get the app on my iOS 16 device to test it there?
