This has been happening for a few days now. When playing drop dead duel strike and I open a multiplayer room and invite a friend to play it goes back to the home area and a black screen shows the 3 white dots for a little while, then I get "We couldn't load friends and parties. Please try again" - no matter how many times I click retry it's always the same. If I list friends from the home screen it works, If I use the ios app it works - it's just if I initiate from inside the game !!! I've tried a factory reset of the headset, set my wifi to 5ghz only, deleted any friends with non-alphanumeric characters in their names - and I only have 12 friends registered at the mo. I've run out of things to try !!!
Any suggestions would be great
