Reading from CloudKit fails under Catalyst

Hi,

I tried to bring an app to macOS using Catalyst, but have troubles with CloudKit. Basically what the app does is, it writes records to the public database and allows to retrieve that data via the recordID.
Simple and straight forward and of course the code has been working for iOS for years now. On macOS I can upload data, but when I try to receive data I get nothing, as if the request was never started. I do not get gate back, nor any error, not even a time out.

Could anybody give me a hint where to look for a solution?

All the best
Christoph
Just upgraded my Mac to Big Sur and can finally run my catalyst app built on a SwiftUI app.

I'm seeing the same thing using Xcode 12.2 RC. I've tried adding the CKQueryOperation directly to the publicDatabase, as well as, adding the op to OperationQueue.main directly after having specified the database as the public one.

None of the operation blocks are firing, recordHandler, queryCompletion, or operation completion handler.
