Hi, I encountered exactly the same issue even though I went through and followed all the steps in: Creating and Deploying a Model Collection - https://developer.apple.com/documentation/coreml/core_ml_api/creating_and_deploying_a_model_collection Discussion of beginAccessing(identifier:completionHandler:) - https://developer.apple.com/documentation/coreml/mlmodelcollection/3649655-beginaccessing and watched many times the WWDC session Use model deployment and security with Core ML - https://developer.apple.com/videos/play/wwdc2020/10152/ iOS: 14.3 (18C66), iPhone 12 Pro Max I even tried to create the test collection at different Teams. All without any luck to solve this issue... As I was going through the Developer Forum, I also noticed that many ML Developers have this kind of issue. CloudDeploymentTest[18290:11523393] [coreml] MLModelCollection: namespace (TEAM_ID.test_collection) download failed. Error Domain=com.apple.trial Code=0 "Unknown error."
