No 'subscribed calendars' under Accounts and Passwords
I have some random calendars on my phone.
These are all listed under 'outlook' when I look at them on the calendars app.
I have seen how to delete these by going onto 'accounts and passwords' but I have no option to look at subscribed calendars, just my email accounts.
How do I go about deleting them?
