Hi, thanks for the feedback. That error usually means what it says: that the iCloud quota for the user account has been exceeded. The error is returned by Apple’s servers and we don’t have control on that, but try checking on one of your Apple devices whether you have space available in your iCloud account.
Thank you very much for your help and the clear explanation regarding the “iCloud Quota Exceeded” error. I really appreciate you taking the time to clarify that the error originates from Apple’s servers and that checking my iCloud space on an Apple device is the appropriate step.
Please accept my apologies for my limited understanding and seniority on this particular technical issue.
