My suggestion is to remove the Region Invite button on the party menu.
(I made this post as a bug report, but it got set to not-a-bug)
^ This happens every time you try inviting a player from another region, and It’s quite normal, but there’s a Region Invites button. If it says they’re offline, there’s no reason the Region Invite box would ever have more than 0 invites in it, deeming it useless. I suggest it gets removed.
Thank you! 
I agree, either make it work or remove it, rn its just redundant. Voted.
Yes, I agree. If it brings no use then there is no point in having it.
I agree! There is no point of this at the moment. My idea if it was here is to make it so you can send invites, use party chat from across regions, and queue into games that the owner queues. (They won’t be able to get in the same game with you, but you can play separately across regions)
This is actually a bug, you can view the report below:
A recent bug report about the issue was incorrectly replied to, but I can assure you this is still something we have logged
