Not to worry, everyone! I just finished talking to a Senior Advisor who has been talking with Engineering. The Senior Advisor assured me that this if this were an issue, Apple would know about it before any customer or developer experienced it because Apple interacts with iCloud billions of times a second. So, to troubleshoot this known issues, Engineering stated folks need to completely remove iCloud from their devices. This does not mean sign-out from iCloud but rather completely uninstall iCloud from each and every device you own, by dragging iCloud to the trash, emptying the trash, and re-starting your devices. Now, the Senior Advisor acknowledged there is no way for the customer to do this. So, because customers cannot follow the troubleshooting steps from Engineering, Apple's Official Position on the Matter is that no further support will be provided until the customer follows the steps provided by Engineering and the customer must keep their devices up-to-date with the latest OS.
