I am having the same issue. EA rep I talked to told me it’s a known issue now and they are working on it. Going to post the issue here also.
Currently I have been using Zach Ertz as my captain and Rivera as my coach. Both show as level 15 out of OD but when I start a matchup Rivera shows up at level 10 and Ertz level 11. While in game, neither my Offensive nor defensive tactics are working. My opponents do not get any challenges when I click on them in game. Also, I tried to switch to Nagy and Shanahan for OD matchups and this happens: I have the specific coaches playbook to choose from but the tactics still show up at Rivera’s tactics and they still don’t work. I have also tried to change to different captain and coach combos and still nothing changes. I have gone through all of the trouble shooting steps suggested by EA and still nothing has changed. I hope that a fix is in the works soon. Thanks for reading. Good luck the rest of the season. Hope many improvements are on the way soon.
