This incident has been resolved.

A fix has been implemented and we are monitoring the results.

We are currently experiencing issues on Edge UI where proxies are not displayed to users with custom roles. Org admin users are not affected.

During this time, non-org-admins on Public Cloud Apigee are not able to use Edge UI to list or manage proxies. Management APIs are functional as expected.
This is not impacting API runtime traffic.

We are actively investigating this issue.
