If you're entering through the Everfall, you need to run all the way to the opposite side of the chamber and kill the pawns that are standing there, on the bridge. The Ur-Dragon will spawn and swoop down on the field after a while.

After its defeat, or after the round has ended, you will need to exit the Everfall altogether, otherwise the dragon will not spawn.

The purple Riftstone in Cassardis is simpler in that regard, as by exiting the chamber, you're also exiting the Everfall. There's also no need to run through the chamber, as you're already appearing on the opposite side. The pawns on the bridge take some time to pop-in, though.

Hopefully some of this helps.
