Hi, I just made two successfull notarizations this morning, in less than 10 minutes : 0d8a6b87-5dcc-43c8-8a1a-58d4a94d2283 d731b45e-9108-4c19-8056-06ba4e7dd16e Suddendly the two latests ones are pending, the worst one is pending for almost an hour: fe89d78a-21e8-4f03-96b7-19a7cc3bd9a0 What is the problem ? S.

Hi, I don't remember how to get the URL of the notarization log given the Request Identifier. How do I get this URL from the command line (maybe with an xcrun command) ? Thanks for help S.
