Unable to delete spam calendar
A while ago I started getting spam calendar notifications. Trying to delete the calendar doesn’t work: when I press “delete calendar” it disappears, then a second later it’s back again.
I found online that this can be solved by logging into iCloud.com, but when I log in there is no calendar app, so this does not work as well.
What might be the problem here and are there any other ways to solve this?
