Calendar issue
Today I went to update an event on my calendar and I have emails, ads, etc. in every date. I can’t recall any acceptance that might have caused this and all self help articles do not offer me any help. I have an iPhone 11 Pro.

If running iOS 13 or earlier versions, check: Settings - Passwords & Accounts - Accounts - Any rogue entries here? If so, delete the rogue account.
If running iOS 14, check: Settings - Calendar - Accounts - Any rogue entries here? If so, delete the rogue account.
