Kind of an esoteric issue I'm seeing. I am a Root Admin but for some reason, after upgrading to Feb 2019 Patch 3, when I log into the Hub and go to Personal -> Work, I cannot see any unpublished apps from other users. I had worked with another admin on an app this way before upgrading but now it is gone from my view. When I go to User Access for this app through the QMC, it says I have CRUDEAO.
I'm also seeing an unrelated issue on my test server with data connections. I create a handful of ODBC connections and another user cannot see them in the Hub despite being a Root Admin and having CRUDO. I make him the owner of the data connections and now I cannot see them in the Hub despite also being a Root Admin and having CRUDO. These seem like such similar issues - did something change with admins' ownership versus their work in the Hub?
Root admin is primary tought of as an backend admin, it got full access to the qmc but not front end. If look at the security rule definitions you will notice that a bunch of the root admin security rules are limited to the QMC only.
You mentioned that you had a different access before. Did you ever make changes to the default security rules to achieve this? It is not recommended to make adjustments in the default security rules, if you want to change you should make adjustments to a copy of the rule and disable the original rule.
