Hello and thank you for the answer. Sure, I will follow the steps and will update here as soon as I have a bug report number.

Hi again! I believe this is the bug number: FB15939005. One thing I forgot to add in the post but I added to the bug is, the Enterprise Key is much smaller than the Developer key, something like half the characters between ---begin key--- and ---end key---. Please let me know if I can be of more support or if I missed something. Thanks again for the help.

Hello! Is any update needed from my side? Thanks!

Hello! Thanks for the response :). It did work with the app-specific password and notarytool. I will try with Fastlane as well, I don't remember if they are 'forcing' the API key approach.

To use this approach with Fastlane, it would be necessary to set some environment variables, as --password is not accepted as a parameter. Thanks again for the reply, it is great to know that there is an option while we don't figure out the API Key issue.

Oh no, thank you for the support! :)

Cool, thanks. I accepted your answer and will close the feedback ticket. Thank you!
