I'm not sure what the issue would be here, I've never heard of this issue, sorry.
FYI I had this issue and it resolved after completing another task, but I cannot for the life of me remember what I had to do. I just assumed it was of the game so I dug my heals in and started levelling up the characters including Ellen. Maybe Ellen is the key here or Kali is the key here as they are both the most heavily involved characters with Android at this stage.
