My real name is displayed to someone who added me as a friend a long time ago, (I disabled the show real ID option weeks ago)
the forums say this issue was recently resolved sept 2020 but it is not as of Oct 2020 (someone left a very unhelpful reply to someone else haven’t the same issue). This bug was verified on computers on the same network.
I’m seeing this too. I disabled real ID, but friends confirmed they could still see my name. There’s also no apparent way to downgrade someone from a real ID friend to a battle.net friend, unless you completely remove them and then send a new friend request. This seems broken.
