Can Blizzard fix this problem or not?

When I want add someone for friend then it writes: “A friendship invitation with that user already exists. (Failed to make initial server connection (Error 2:5005))” And who I want to add that also wants to add me and the same problem appears for him.

Confirm the friend request via the launcher
Also make sure both of your regions are America’s or the same region. (Located above the play button)

Oh okay thanks, I already got it.
