Hi Leo,You should contact enterprise support for assistance. I believe
we have to configure your integrator ID for DPS 2015 which is why you
aren't seeing the sign-in button in the apps.As for the protected
content being displayed, are you using the preflight version of the app
(did you check preflight in App Builder?). If so, try with it turned
off. We don't enforce entitlement and access control in preflight apps.
Enterprise support should be able to assist with this as well.Neil
