Based on the response I received today to my request for technical support, it seems that there are some ongoing problems with CloudKit that Apple is investigating.

You should see an update in your feedback request shortly, but in summary, 98% of your errors are Quota Exceeded, when attempting to upload assets into CloudKit. This occurs when a user is out of iCloud storage.

It is essential to properly handle error messages from the CloudKit framework to give the user the best experience when situations like this arise--please take a look at https://developer.apple.com/documentation/cloudkit/ckerror to better understand the errors coming back from CloudKit framework and ensure you're not blindly retrying operations for situations like this.

No, this is not related to the "Quota exceeded" errors. I am aware of those and already handle them, since many people don't have enough iCloud storage and my app uses a large amount of storage. The problem I'm discussing here is the "status 500" errors that occurred for about a week and rendered my app useless, and then suddenly stopped happening. And now there is a different problem: CloudKit notifications are not being received by my app. These have always worked before and suddenly stopped working around the same time as the "status 500" errors. I'm still waiting for a resolution of this problem, which has disabled an important feature that my users rely on.

We'll have to discuss in your FB since this is a public forum and details of your app cannot be discussed here.
