Our app supports iCloud CloudKit sharing and provides URLs of CKShare records to users (e.g. via UICloudSharingController). Clicking on the URL in the Apple Mail or Messages app in macOS or iOS works fine. Pasting the link into Safari on iOS also works fine.
But including the link in a web page or pasting it into Safari or Chrome on macOS or Edge on Windows 10 (we have a fall-back web site for non-Apple users) results in a fatal "iCloud has stopped responding" error page displayed in the browser.
The app is a "universal" app and is available in both the Mac App Store and iOS App Store. All the CloudKit features otherwise work fine on both platforms.
Does anyone have an idea what we might do to solve this? Do we have something misconfigured somewhere?
I've also submitted a DTS Technical Support Inquiry #735184444 and Feedback #FB7697827.
