I was thinking that it was a duplicate that was named as ‘US Holidays’. Because there are already US Holidays that are set to each account that is setup. This one in particular at the bottom of the list under “Other”.

Even weirder it does show under Fetch Data in the accounts tab but does not show otherwise. So i dont think i can delete it.

So it appears as ‘Other’ under the Calendar app. But when I go into Settings-> Calendar, it does not show the ‘Other’ account. No clue how to remove it.

I just checked and the only accounts that pop up when I click Calendar are my own email accounts. So not entirely sure what happened.

I just refreshed to test cause i was genuinely curious.

It modified “Subscription Calendar”

I will but a bit worried as it was under the Apple Id and don’t want whatever script it just ran to remain there after resetting.

I dont understand how it did that. Only Apple certificates are trusted.
