Step 1: Pick a level and play through both Story Mode and Free Play (while collecting all Minikits) The suggested workaround is to renew your game license to gain access to the level (Settings - Account Management - Restore Licenses).
There are reports that updating to Patch 1.06 is locking people out of the Agents of SHIELD level. The majority are nestled in with other levels but the Black Panther level is on its own near the bottom of the globe and the Agents of SHIELD level is near the Korea Prospects level. Going to the stage-select globe will not automatically take you to an unplayed level so you will likely have to search for the new levels. The DLC levels are mixed in with the regular levels on the stage-select globe and are placed based on where the level takes place geographically. All of the levels are considerably shorter than the levels in the main LEGO Marvel Avengers game so no matter your level of experience with LEGO games, you will blow through these levels fairly quickly. There are six DLC levels for LEGO: Marvel's Avengers, focusing mostly on characters who have either recently had films released or will have films released in the next few years. Red Bricks can be used to speed up the process. Do trophies stack?: Yes, the PS3 and PS4 have separate trophy lists but the Vita version never got any of the DLCs.Glitched trophies: 0 but take note of the walkthroughs for the Minikit related trophies.Number of missable trophies: 0 (Free Play).Minimum number of playthroughs: 2 (1 Story Mode, 1 Free Play).Approximate amount of time to 100%: Estimated trophy difficulty: 1.5/10 (Personal Estimate).
