I can't seem to add anyone to my friends list via battletag or R.ID. I've tried sending a battletag invite first, checked and doublechecked the spelling, but they don't get a pending invite on their end. Then I gave them my battletag and they tried to add me, same result, invite sent but no confirmation on my end. Finally I tried R.ID with this person, and I get exactly the same result, no confirmation on their end.
So, is there something I am missing here or are the R.ID/Battletag invites borked?
