My ICLOUD login ID has recently changed to "me.com"
In addition to THAT, I recently updated my ICLOUD space but now I am receiving notices that my space on ICLOUD is now exhausted and I need to update my ICLOUD again....Whats going on here anyway?
By default, that has always been an Apple ID.
Device or computer?
What do you see at System Preferences/iCloud/Manage
or Settings/Your Name/iCloud/Storage/Manage Storage
