Xbox app parties

Hey, I’ve been having issues on the xbox app and joining my friends parties lately. Every time I receive an invite and I accept, it says their is an error, or that everyone in the party is disconnected except for me. I’m really getting frustrated at this
because I cant communicate with my friends Please try to fix it or give me some feedback on how to fix it myself if it’s an account issue. THANKS SO MUCH!! -
