Welcome Back Pass Missions Missing

I recently returned to the game, and have had access to the Welcome Back Pass for some time now. However, there appears to be no way to see what the missions for this pass are. There is no tab on the top, (Just “Pass”). There is a section right before the next unlock saying Complete 5 Missions to unlock step x, but nothing to show where the missions are. There is a “Daily” button right below that, but that is dead, and does not do anything.

I have limped through the first 10 levels by pure luck, but no idea what missions I have actually accomplished or what I need to do. Completing the Tyrant pass missions is not rewarding credits there either, so I know they are not linked.

What needs to be done to view the missions for this pass?
