Unable to invite friends,invite button does nothing.

I have progressed enough way through the campaign's to be able to invite a friend to play Co op but when I press the invite button nothing happens, it just makes a noise like it's been pressed and then nothing. I'm also unable to invite online players into battles..
I'm playing on the Xbox windows games pass if it helps.

My gf and I are having the same issue, its the same in the Battle mode. Invite player just makes a noise and does nothing. Even manually opening the game bar doesnt help because the invite and join options in there are greyed out.

Its a shame it seems nobody at focus has seen this, I really would love to play co-op
