When you go to http://mytools.management and click on Who Am I it should tell you what policy you are on.
Then on the adam:ONE Dashboard select that policy and check what rules are enabled on it. If it’s a whitelist policy you would need a rule that allows paypal, slack, etc.
You can create new rules by clicking My Rules on the left hand side.
You can also find our user guides here adam:ONE Operational Instructions and Guidelines
