Unable to edit AP on defense???!!!!

Is anyone else having the issue in Team Line ups where u can't edit AP in defense, there's not even an option for me to go into the AP section... Cheers

Yes

Apparently you can’t ”stash” extra players that aren’t in your main lineup in the specialist tab.  If you go over a certain number of players on your roster that happens.  Try removing a player or two and it should come back.

See above, but you don't have to remove extra players, if you edit the ability on someone you should see the option become available again. 

I removed an ability directly from someone's card in my lineup and added the one I wanted and I was able to get the option to reappear so I could activate the new player.   After that,  the option disappeared again.
