Spam iphone calendar invites that I cannot unsubscribe or delete
I am getting multiple spam iphone calendar invites with alarms for multiple days and have done everything apple states to do.
- There is no “unsubscribe” option on the spam calendar event.
 - There is no unwanted calendar on my iPhone or MacBook, just mine.
 - I cannot block the email address (there is one, but I can't block or report it).
 - I can decline the event, but everything online says not to interact with the event, including not declining it.
 
I followed similar problems from users as recent as January 2024 and IOS 17 supposedly solved the issues then...I have IOS 18 now and I'm having these problems.
Apple instructional videos are outdated and don't address the problem, at least not those I've found.
iPhone 14 Pro, iOS 18
