I ended having the same issue with the supply drop, i think it has something to do with when the account was created, bcs on a alternate account of mine it worked alright
For updates on the 10x10 supply drop issue causing some players to not see the supply drop calendar, check this thread: https://forums.playcontestofchampions.com/en/discussion/383103/the-10-champions-drop-bug
