So since April 5th i have been having on and off issues trying 2 join/Invite a few of my clan mates we have been able to trade an join another for years now. But for some reason we have been getting could not deliver invite's almost everyday. I am on PS4 they r on PS5 im not sure why this is occurring or what causes it, sometimesit'll let me oin or them join but if we try and add a 3rd person it could take a while to be able to join if it lets them at all. We tried resetting our Crossplay and Waframe accounts but no resolution. Anyone have any suggestions??
