Friend 2 things can happen:
1- There are no Coa missions.
2- you have not yet enough in the game to get missions out.
Another thing would be the events of Coa: it is possible that your Coa finished the event ahead of time, the events have a duration of one day but if the Coa reaches the maximum number let's say in 1 hour the event ends but the next one does not start until the other 23 hours pass
