I used to be able to post keys from my group, but sometime recently, I can no longer do this. Pressing the button to post just does nothing. I have the authenticator, obviously. Is this a bug, or did you remove the ability to post keys that you don’t have? -S
When posting a key that isn’t yours you have to post it under the mythic dungeon category now instead of mythic+. It only lets you post in mythic+ with your own key if you’re the leader. I’m not sure why, but I noticed that the other day. People still see it and join though unless they’re using an addon and filtering only the M+ category.
