Apple IOS 13 CALDAV reminder/ tasks not updating
Ever since up I updated to IOS 13, my CALDAV synced reminders/ tasks do not update. I can download a copy of the tasks but any changes made on the device are not synced and any changes made on the webpage or other deivce is not shown on the iPhone.
I have found these two articles which suggest it is a problem with certificates. Does anyone know if this is the case or is it something else?
