You can drop down to Level 2 if you have not met the Level 3 requirements in the last 100 days (the requirements are outlined in my previous post). There is also a 2-week grace period immediately after you gain Level 3. Your account should now reflect your Level 3 status.
If you are concerned about no longer having access to the Iceberg Lounge upon dropping down, you can find more information about getting around our pesky bouncer here: https://community.dcuniverseinfinite.com/t/how-to-enter-the-iceberg-lounge/
Unfortunately, there is no feature that allows users to view their progress toward clearance levels at this time. However, you can always ask the moderator team to provide you with a snapshot of your current progress.
