I want to invite a friend, have never had any problems on both console ps4 or xbox, finally got it on pc. There is not an option to invite. Both characters are seasonal. We have had quick join on and off and reset the game multiple times but when pressing “O” and right clicking on their name or any friends name there is just the standard Send Message, Invite to Conversation (greyed out), view profile, view achievements, etc. I needa lil helps
If it is a new install, it may take a couple of days before Invite activates.
This has also happened to me every so often, usually when one of us has been playing and the other logs in.. The workaround was to have my friend and I both completely leave and restart Battle.Net
