Unable to view/edit other users Apps

[cbn_timsmith]

We have two Admin user accounts in our Test environment, who previously both had Root Admin, and Content Admin roles assigned to them. They could both view and edit all Apps in the work folder. We since updated to the February 2018 patch 1, and now we can only view and edit Apps that are owned by us. What has changed in the latest update that has stripped our access to other apps?

I tried adding a new role called 'Super Admin' that behaves the same as Root Admin, but also includes hub context, as we suspected that Root Admin used to also have hub context, but this has changed nothing:

Here is what shows under Audit:

with the users in red being our admin accounts.

Any advice?
