If you can’t add another friend, you’ve most likely reached the maximum number of friends allowed on your account.

What you can do:

• Check your Friends list and see if it’s already full.
• Remove one friend (for example, an inactive player) and try adding the new friend again.
• Fully close the game and reopen it to refresh the Friends list.

Important notes

• Once you hit the friends limit, you won't be able to accept new invites until you free up a slot.
• If you removed a friend but still can’t add a new one, the list may need some time (or a restart) to update.
