I'm considering using CloudKit to share documents across an enterprise (hundreds of users) and am hoping that someone that has had some experience with this API could share their experience. I'm especially interested to know if there are any constraints such as:
1. Is there a maximum number of users that a document can be shared with?
2. Can I include multiple documents in a CKShare subscription? If yes, is there a limit to how many documents can be included?
3. Are there any file size constraints in terms of how big the file can be that will be shared/synced?
