I actually just found one
, and it turns out they're missing more than I thought on Comixology.
Captain America & The Falcon 5-7
Iron Man 84-85 and 86-89 (84 and 85 are a AD prologue and 86-89 deal with it's aftermath)
Captain America 29-32
Fantastic Four 517-519
Spectacular Spider-Man 15-20
Thor 80-81 and 82-85 (80 and 81 are a prologue and the others are a parallel story)
