Cant invite friend to my guild

Put in his invite code and says exist but when i hit invite says cant find user…

Are you using underscores instead of spaces? I’ve heard that the underscores don’t appear clearly on consoles.

Yes…put it in just like it shows…when first goes in says exist…then when i hit invite says user not found

I have this same problem i made my friend leave the guild he created to join me and i cant invite him hes not happy about it did you mangage to sort tthe problem
