From d4ffe61d4fb71953bff0f94ff5d1603afe7d46f7 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Mon, 5 Mar 2018 15:42:57 +0000 Subject: [PATCH] Remove ability for AS users to call /events and /sync This functionality has been deprecated for a while as well as being broken for a while. Instead of fixing it lets just remove it entirely.
