Just unlocked this! Here's what I did.Good to hear Hanz! I've read quite a few posts that by playing the weekend playlists it "resets" "reboots" the sync in a way or something because they are constantly rotated in and out, not sure how much truth there is in that but regardless glad you got it unlocked! gg and to anyone else reading and stopping by there is still hope for ya!
Turned on Xbox did not sign in.
Cleared blue ray persistent storage.
Removed my primary profile.
Hard reset (hold power button down til it turns off ..about 10 sec.)
Disconnected power cord for 10 min
Plugged it back in & turned it on.
Redownloaded my profile.
Loaded up halo 5 (never uninstalled it.)
Closed message of day window & waited for it to sync up with server.
Played a match in heroic ff & mythic ff but it didn't do anything so I went to standard Warzone got stormbreak & won suddenly BOOM! 33% !!
GOT A R C WON 66%
FINALLY got Apex & won "UNLOCKED!!"
NEVER LEFT LOBBY or opened any packs just waited for next map Everytime until I got all 3 in 1 sitting!
Hope this helps!
If it doesn't work keep in mind I did it during a MYTHIC WARZONE weekend.
Now that I'm unbanned here 🤣🤣
I can confirm this method works & needs to be done on Mythic weekend.
I got it late Sunday night / Monday morning just before mythic left rotation.
I also tried on my old profile after mythic was gone & it didn't work.
So Mythic weekend is definitely the key to it!
