Earlier, I tried to complete the Atlantia dungeon with two friends, the warning at the start said it would take 1.5 hours, after two hours we had still not finished and we had to leave, causing us to lose all progress in the dungeon. Is there a way to pause the dungeon and finish it at a later date?
There is currently no way to pause your progress inside any dungeon.
Once you leave by exiting or quitting, then as you're probably aware, the dungeon restarts.
The only way you can temporarily leave the dungeon though is by fleeing/getting defeated or teleporting to a common area (not inside another dungeon or boss instance). In such an event you will have 5 - 30 minutes to return to the dungeon (using dungeon recall) before it resets.

Sorry to hear that
Unfortunately there is no way to pause and resume a dungeon. Maybe when you try again it would help to have a fourth with you. If you'd like me to help just let me know and I'll happily help you
