My trophies are not importing over to the UNCHARTED: Legacy of Thieves Collection even though I have imported my save(s) from UNCHARTED 4: A Thief’s End and/or UNCHARTED: The Lost Legacy. What can I do?

Please refer to these articles to make sure your save data import was done properly:

Importing Save Data using Cloud Saves with PlayStation Plus

Importing Save Data using USB Flash Drive or External Hard Drive (PS+ not required)

If this was done properly and your trophies still aren’t popping, please make sure ALL of your save files have been imported, if you have multiple. 

Please be aware that trophies will not import to the UNCHARTED: Legacy of Thieves Collection if the player used Encounter/Chapter Select when unlocking these trophies in the PS4 versions of UNCHARTED 4: A Thief’s End or UNCHARTED: The Lost Legacy. Some trophies may also be associated with a specific playthrough of each game, and may not transfer also as well.
