after 4.3, Calendar notification on lock screen won't go away
Hello everyone, I have an unlocked (Global) HTC One and recently updated it to 4.3. I don't use the calendar at all but last night a notification for Columbus day came on in my lock screen and I can't get rid of it. I looked through all the settings and turned off notification of all kinds! But the damn thing is still there.
Any ideas on how I can get rid of these calendar notifications?
Thanks in advance!
