AC App can no longer post in thread

anyone else have the issue since updating to N? I dont get the little green box bottom right to post, i do get it for creating a thread. Im doing this from my PC, kinda annoyed. I uninstalled the app, reinstalled and also installed the AC forum app...nothing works. Only happened after i updated to N. Was searching threads but couldnt find similar question, didnt want to create a new thread but its driving me nuts.
