Admiral Ackbar’s capital ship fleet challenge

Hello, I completed the first fleet challenge for admiral Ackbar’s capital ship but never received the home one blueprints so I can’t upgrade him and do the next challenge but the game has acknowledged that I beat the first tier and can’t replay it so I’m stuck and can’t move forward with the capital ship challenge but also can’t go back. The blueprints are not in my inbox either so I don’t know what to do going forward.
