We have a managed (i.e., Apple-hosted) on-demand asset pack (via Managed Background Assets) that we download at the start of our iOS/macOS app. We first present the user with the download size and the option to download the asset.

The iOS version of our app went through review just fine, but the macOS version (Catalyst) is stuck.

The reviewer reports an error that indicates that even the lookup of the asset pack (assetPack(withID:)) doesn't work. On all our test devices we don't have that issue.

It seems the reviewer is running the app in an environment that is unable to load the asset pack information from TestFlight.

We don't know what to do here. Any help would be appreciated!
