Note how Uri is always in the position of the advisor. He speaks in half-truths and withholds information. Y'shtola even asks Uri if he's lying to the Scions to manipulate them at one point in Shadowbringers. All the hints are there.
But all of that is resolved within Shadowbringers - and with a lot of apologising afterwards. It's entirely clear why he held secrets and couldn't let you know things at the time.
