So I've now received another spam invite into my calendar - as well as the iPhoto invite a couple of weeks ago. Both into my new apple id which is a new email account that I have never used for anything else. I've spoken to Apple Tech again. & a very helpful advisor Sharee Davenport, advised that there is no known resolution for this as yet. She said Apple is working on it (but has been for a long time). She also said there are a lot of people out there getting these & that she is one of them! She sent me a link to send screen shots of the invites & has logged this with the engineering/tech section & will contact me when/if they come up with a solution. Once I've sent screen shots I can go ahead and delete and keep deleting until they can solve it. Not ideal at all. Also, she confirmed that tech support doesn't read these blogs - it's here for us as a community to help each other. So the only way to log your frustrations is to send them to apple feedback. 😟
