On both my iPhone and iPad running latest public betas for iOS/iPadOS 13, I keep getting nagged about a site called my.punchbowl.com, which to my knowledge I don't use. It seems to be an online invitation site and I did find a few emails from like ten years ago, that I manually deleted. But even after the email deletions, I keep getting the nag. When I click on the dialogue box to continue, nothing ever happens. When I click dismiss, it does just that, dismisses the dialogue box. How can I make it stop?
