Upon logging into a Veeva CRM (Salesforce) org, a generic insufficient privileges error appears. Any attempt to navigate results in logging out from the org.
The issue is caused by the API Only User Administrative Permission belonging to the user's profile. In order to resolve the issue, this permission must be unchecked.
Note: This permission can only be granted to the user's profile using a permission set in the event it is an SFDC Standard Profile.
