All
Per the subject line, I tried to turn on Messages in iCloud but get the above error. I am using the same account for both. The only difference is that as this is an old @me.com Apple account that iCloud is somehow reverting the new @iCloud.com version to @me.com for that login whereas messages is using the new version of the same account @iCLoud.com. For Example:
iCloud login shows: name@me.com
iMessage shows: name@icloud.com
Again same address jsut for whatever reason when I enter the @icloud.com in the icloud login it reverts it to the older @me.com domain. Thats the only possible issue I see that could be causing this.
Anyone else seeing this and have a workaround ? If not I'll file a bug
Thanks
