Our manage-hosted production system was updated to April 2017 Q2 CU2 in mid-August. Although we had tested this release on our staging servers, there were plenty of problems left to find. Unfortunately, this release is quite buggy. This discussion are is for others who are at the same release or contemplating upgrades soon.
Emergency update to CU3 on September 17. Authentication issues resolved. Other problems remain.
